Is Mac OS X Slow? 1229
Junks Jerzey asks: "Every time there's a mention of Mac OS X on Slashdot, there's a flurry of responses about how unbearably slow Mac OS X is. To anyone who has done software development under both Mac OS X and Windows or Linux, is there any truth to this or is it simply a knee-jerk reaction from non-Mac users who see low numbers like 800MHz. I'm talking about average priced Macs here, like the LCD iMac line, not the dual 1.25GHz machines that sell for $4500+." Having the fortune of using a Titanium Powerbook for over a month, I don't find Mac OS X that slow at all, however, there are some things that do take a little longer than I am used to, but I think these things are application-specific. For those Mac OS X users out there, have you noticed operations that seemed slower using Mac OS X compared to similar operations on other operating systems?

Mac OS X is based on a Microkernel - now everyone agrees these are slow, right? Well, sure I can see where that's coming from - but Apple have gone to great lengths to make this as fast as possible without losing the benefits. So the Kernel isn't actually slow, it compares well with other BSDs and Linux.
The Mac is only 800MHz(ish) for low end machines so it must be slow? This is the classic "MHz Myth" the G4 has a short pipeline (a good thing) and executes over 90% of it's instructions in 1 cycle or less (the modern definition of RISC, TRIVIA: the old definition was implements less the 100 instructions). And then there's the amazing AltiVec (which Apple call the "Velocity Engine", if you see these terms they refer to the same thing). Macs have blistering real math performance (the G3 iBook doesn't have the AltiVec).
Macs are based on Objective-C - that's REALLY slow. Well sure if you just implemented Objective-C without optimisations then it would be slow, but NeXT (them that did the Objective-C implementation) didn't do that. They added a method lookup cache which speeds things up a great deal, and IMPs that can be used in tight loops to gain extra zip (healh warning, IMPs are not ususally needed and can cause stunning bugs if you're not careful with them - unless you have a large tight loop that REALLY needs speeding up - don't bother with IMPs). The use of allocation zones can also speed up the VM system a great deal (these aren't as troublesome as IMPs can be, but again aren't as often needed as you might think). The Kits make heavy use of these tricks so they are pretty fast.
Quartz has lots of tricks to make it fast, and now all current Macs can make use of Quartz Extreem (uses the compositor on the GPU to dramatically speed up the whole windowing system).
So no Macs aren't slow. Apple's site includes server stats and they are very impressive too.
But the implementation details aren't widely understood so a lot of people's initial reaction is "Oh that's gotta be slow" - it really isn't.

The fact that it is based on a microkernel doesn't matter, because the Mac OS X kernel is not a microkernel anymore. The whole kernel runs in one address space (so no message passing between different kernel components), just like in Linux. They still kept the different parts of the kernel more or less distinct in the source, but this is simply for easier maintenance.

While the P4/Athlon and (I assume) G4 can all run more then one instruction at once (not just one) that's irrelevant, what is being asked here is if the OS is slow for the hardware it's running on. Win95 would be blazing fast on a p3-500 with 128 megs of ram, but XP would run like a hog on the same machine.
Since I seriously doubt anyone has any kind of actual measurements this is basically going to be nothing more then a page-view generating flamewar on slashdot.

You have to understand where I'm coming from. I'm no fan of Microsoft's practices or the stability or security of their code. And I am a big fan of OS X technology. A (mostly) user friendly operating system backended to a unix system, with all the unix tools and features I love. Plus I'm not railing on the hardware architecture or the OS core. Codewarrior on OS X beats the pants off Visual Studio on Windows in just about every category. But OS X's Finder, its front door as it were to someone like me, has some serious lacks.
I'm pretty fast in Windows explorer, I have to be navigating between hundreds of source files. I've learned just about all the shortcut keys and my hands move to wherever is fastest to accomplish a given task, mouse or keyboard. When I started working on the mac I was frustrated by the amount of mouse effort I had to expend. If my hands are on the keyboard and I need to do some UI navigation I don't want to have to use the mouse. I call that poor UI. I know there are probably keys there I don't know about, but they certainly aren't readily apparent in the help files. The tab between controls functionality windows has seems to be largely missing. I'm not incapable of learning new shortcut commands, I just need to be able to find out what they are without installing 4 third party applications that add them.
The seoncd part is that the finder is just damn slow. I don't care that its shiny and round and scales perfectly. I have a ~500Mhz G4 and thats more than enough power to make sure that simple tasks like moving files around and editing source code should never EVER have a perceptible delay. Sure, maybe Windows XP might be slow on an equivalently powered PC, but you know what? I can turn off all the UI crap that comes with XP. Not so with OS X. Its about as customizable as your grandmothers sofa, the one with the plastic covering you're not allowed to sit on.

If an app is running a huge calculation, you can still web browse. iTunes doesn't skip. You can play DVD on your background (you have to set your background color to a specific value, start up the DVD, then hide the DVD player). You put a really pretty fish tank OpenGL screensaver as your background. Running many mpeg4s at the same time doesn't choke the system. It keeps going, in fact if you just add ram, like with any Unix system, you can throw any number of big jobs at it, and it will keep going.
That being said, you have to wait for the genie effect to take place. Because it's a friggen animation. Same with icon removals from the desktop.

Unfortunately, it comes from Apple, which means it only runs on expensive custom hardware, which makes it useless to most of us, who will have to wait for Linux to reach a more mature level. It's interesting that OSX is more useful as a desktop Unix than Linux is (for the non-technically-inclined user, someone who may be technically competent but not used to ripping things apart and making them work when they're broken) even though it's fairly new, whereas Linux has many years on it and still has a lot of stability, speed, compatibility, and usability problems as far as the desktop goes.
On the other hand, MacOSX had NeXTStep to work with. While there was an x86 clone version of NeXTStep, as I understand it was fairly tightly bound to a small selection of hardware, making it a more similar product to MacOSX than it might at first appear, and of course it was best-known for running on the various NeXT slabs and cubes, which might as well have been next-generation macs.
So yes, since it aims to fulfill all our dreams of what an OS should be (fast (maybe), easy (yes), powerful (certainly), stable (maybe)) it does justify this number of stories, and more.

My observations (Score:5, Interesting)
I think the question is really one of perceived speed. I noticed that on the AMD box, and Win2000, the common behaviour for screen draws is to wait until the operation is finished, then draw all-at-once. For example, IE, when loading a page, will remain exactly as it is (the current page you're on), until such time that it loads Slashdot, then draws it in one fast swoop.
Now, OS X does this as well, but it tends to give more feedback. The browser window will turn white, then the banner appears, then graphics and text. I've timed both boxes - they render within a half-second of each other (again, subjectively). The OS X box could easily give the impression of slowness. But it isn't really.
There are some things in OS X that need improvement - notably window-sizing - but then again, the Win2000 box still does outline-drawing for resizing so it's not fair.
In the end I think Quartz Extreme is Apple's answer to this. Quartz does a hell of a lot more work than the current Windows drawing scheme, and it looks a hell of a lot better. When OS X first appeared, many lamented the excessive eye-candy. Now we have a scheme where your normally-dormant hotshot GPU is helping out with drawing the OS. It makes a gigantic difference, and takes a major load off the CPU. But it is version 1. It will get better.
I expect Microsoft to go through similar growing pains when they go for the photorealistic desktop in Longhorn.

It gets even worse when your off-screen drawing touches every pixel in your window. Apple encourages apps to do this, of course, by offering particularly gluttonous Aqua features like brushed-metal windows (Extreme has no way to ask the graphics hardware to chew on a full-window gradient, atop a texture, being rendered to an offscreen pixmap). Don't believe me? Fire up Quartz Debug (part of the developer tools; allows you to ask Quartz to highlight update rectangles before they're painted) and see for yourself.
I'm confident that Apple will continue to make improvements, but right now apps like iCal (which shouldn't be computationally intensive, but is all hopped up on Aqua) are miserably slow in screen updates.

I had an Athlon 1.x Ghz up until last December with all the bells and whistles a gamer could reasonably want. XP Home started freaking out on me and after a while and many calls to Microsoft I basically determined it was beyond repair for me. I've been using computers and building my own since probably 94-95 or so so I should've been able to fix anything reasonable. I'm pretty sure ultimately it was a hardware problem but I was fed up with Windows anyhow so I just sold the whole thing except the motherboard/processor (everything else worked fine).
No more computer for me I said.
Then I saw the iMac. It had style. Maybe person X doesn't like it because it looks like a lamp or a funny hat or whatever, but it's certainly unique and has some style. And I knew it had Unix underneath that pretty screen. I had tried various releases of Linux but it seemed like after the many days of tweaking would ultimately end in me booting into Windows anyway. No point in that. But the iMac came with Unix (BSD, Darwin, whatever you wanna call it, that's not the point) installed on it.
So I bought it. And it arrived. I took it outta the box and was even more impressed with the real thing. Within minutes I was literally up and online and everything worked. I really was amazed.
The above is mainly to establish that I used to use Windows, dabbled in Linux, and am recently a novice Mac freak. So now more onto the question at hand.
Of course all the iApps run well. Not a problem there. I have never ever ever ever ever had a coaster CD or DVD from this machine. This happened quite frequently with my PC. While burning a CD under Mac OS X I've been able to browse the internet, watch quicktime, etc no problem even. I *think* once I even played an OpenGL game to see if I could make it make a coaster. No dice though. This makes me happy. A coaster for a CD isn't that big a deal but coaster DVD's at $4-$5 a pop can stink.
Why do I have 768 MB of RAM in it? To run Windows 2000 with Virtual PC. Windows 2000 does run slow. It works but it runs slow. For my correspondence classes I'm taking right now I need to program in VC++ so I went and got Virtual PC. VC++ is the only thing I use Virtual PC for.
I recently purchased Macromedia Flash MX. Works like a charm. I don't notice it being slow in the least.
Exporting DVD's from iDVD can take a while. But I don't really have a comparison on the PC so that's probably not too helpful.
I've rendered some Bryce here and there and it doesn't take any longer than on my Athlon machine that I used to have. I won't say it's faster but I know it's not slower.
Games that my machine meets or exceeds the specs for work just like they did on the PC. The Mac does have games... you can get them from gogamer.com and adobe.com...
Encoding to MP3 doesn't take any longer. Converting movie files takes the same amount of time.
I dunno. Overall I'm impressed with OS X. It took me a while to realize that it wasn't the computer I was happy with but it was the OS that I was happy with. If you live close to an Apple store I'd reccommend checking them out for yourself or finding a friend that'll admit to having one.
As far as speed goes I think they're decently on par with x86 machines. They might be a tad slower. But unless every single day you're going to render video, does it really matter? All I usually do is browse the internet, download stuff, play the occasional game, IM, etc. If you want to play every new game that comes out I'd say get a PC because you can upgrade that easier long term I think. Or if you daily intend to do super intensive tasks. But for most users any small slowdown that a OS X does is worth the benefit of which in my opinion, is a better OS.
It's like I told my friend the other day... I might have a *insert crappy but dependable car name* and you might have a *insert fast but non-dependable car name*... but odds are, neither of us are gonna very much over highway speeds so who cares if you can go twice as fast as I am if you never will.

Since I was buying a cluster my criteria was not single processor speed but speed per dollar what i found was mildy surprising. For programs that could take advatage of the altivec chip inside the G4, the mac was about a factor of 2 cheaper per run time than the P4 and athalons. On the otherhand with the Altivec turned off the mac was about a factor of 2 more expensive per run time. I note that this was not done on code optimised for the altivec but was just generic fortran passed through an automatic vector pre-processor program for compile time optimization.
Of all the processors I tested, P3, p4, athalon, the P4 had the wildest variations in benchmarking. that is all the other proceesors seemed to have constant scaling factors in speed as the applications varied. but the p4 variev by over a factor of 3 from the others both faster and slower. I assume this has something to do with the very long pipeline, and the hyper threading, and the size of the caches. But even taking these into account I found it highly unpredictable which applications would run faster or slower (that is ones that might logically have more cache misses did not neccessary degrade)
. In the end I decided the P3 has the most bang for the buck , though falling cpu prices might shift that conclusion to the athalon. The problem I encountered with the athalon was a higher down time for the cluster units due to thermal faliure., so thats a hidden cost. The apples NEVER failed in any thermal tests so thats a hidden plus.
Now this analysis does not factor in other things like Graphics speed other factors more important to users than sceintific apps. However when I compare my molecular visualization grpahics before and after the release of 10.2 I have to say the mac is insanely fast for graphics now wheere before it was intolerably slow.

That said, my own personal opinion is that it's fast enough for me. I run it on a G4 733 MHz tower and a 600 MHz iBook. In general, speed is such a non-issue that I never think about it. I have plenty of things on my wishlist for OS X to improve, and while speed is there, it's not terribly high. I don't find myself ever frustrated by a lack of speed with anything. I use iMovie, iDVD, XDarwin, Mozilla/Chimera, Quicken, iTunes, Terminal, and plenty more pretty extensively. Again, take my hardware, OS version (Jaguar) and personal biases (like Mac, OS X) into account.
Even so, lately the iBook has been taking several seconds to login, where it used to be about 2 seconds when we first got it. Not sure why, but cleaning out ~/Library always seems to help. If not that, then it's probably something in /System or /Library. I'm not too thrilled that OS X seems to exhibit its own version of "registry rot," slowing down over time. I'd like to say that sort of problem only afflicts MS users but it's not my experience with OS X. Hopefully they're working hard on fixing and optimizing this stuff - and before it gets to a point where I do think it's too slow!

But I do a lot of Java programming and the Mac is retarded slow with its Java compared to just about any other system out there. Even the newest one - the newest one seems to have even slower OpenGL somehow.
I also don't like that Mac has Java 1.3, and from what I can tell, you are fixed at that until they decided that they will upgrade it in their own release, regardless of the fact that there is 1.4x out for sometime now, which actually has a lot of things that some of us need and use.
All in all, I think the Mac is plenty fast, after all it is stupid to look at only the nominal speed of the processor. Look at Seti or Distributed net -there you can see that the G4 and G3 kick major ass, largely due to their much larger cache size.
And for everyday use, the Mac seems like it is just fine.
But when people say it is "better" I'm not sure I agree with them - I no longer think it sucks (OS X is pretty nice), but it isn't really of any use to me until either it becomes cheaper than a comparable PC system, or until it becomes faster than a comparable PC system.

Musings on CPU and UI Performance (Score:5, Insightful)
First, let's get my biases out in the open: I am a Macintosh user by (recent, OSX only) preference who's also perfectly comfortable assembling Linux or Windows PCs from bare motherboard and case right on up. I prefer UNIX-based operating systems for their stability and openness, the more stable and open the better, but find Windows inevitably the best practical choice for some situations.
I won't comment on disk and memory performance; others here have handled that ably, and I have no experience with MacOS X in very high load situations.
Processor Performance
This is the one that's subject to the most advocacy; raise your hands if you haven't heard the term "Megahertz Myth". Any hands up? Didn't think so. (Apple advocates aren't the only folks who like it; you'll hear it from AMD lovers, too.)
G3 and G4 processors run at far slower clock rates than P6-class processors. This much is objective. What Mac advocates like to claim is that G3 and G4 processors are much faster, clock for clock, than P6-class processors. The problem in evaluating this claim is that it's both false and true at the same time.
The G3 and G4 are not faster than P6-class processors at typical integer and floating point operations. They're just not. In fact, they tend to run (slightly) slower, clock for clock, in SPECmarks. They're only faster in one specialized world. The catch is, that specialized world is a major one.
Vector and matrix operations are useful in a ton of multimedia applications--most particularly image and video editing, but there are other applications as well. The G3 and G4 have much better vector units than P6-class processors. Not better, much better. This is why Apple always uses Photoshop as their benchmark: a G4 running well-optimized vector math is entirely capable of spanking a P6-class processor running at twice its clock speed or more.
So the answer to this question is that there is no definitive answer. Mac advocates will claim that graphical operations are the slowest things anyway, and so optimizing them will give you the most performance benefit overall. PC advocates will make the generalist argument, and include the (true) fact that an application must be hand-optimized for the G4's vector unit to see these performance gains.
Overall, most people think the G3 and G4 are slower for most purposes, and that the Mac won't have a serious chance at the top of the performance heap again until its next round of processor upgrades, coming next year.
UI Performance
This is the performance most people notice. I'll hit several areas of it, since there are tradeoffs.
First, the good. Aqua's overall responsiveness is probably the best of the three major windowing environments. Any of them can feel like they lose clicks or take forever to process them at times, but it generally feels like it happens less with Aqua than with either Windows or X. (Note that in X it's heavily dependent on what your desktop environment is--but most people like to use either KDE or GNOME, both of which have responsiveness issues.) Aqua also redraws on application switching faster than Windows does, and at about the same speed X does, since it handles open frames in much the same way.
Now, the bad, and it's significant. Aqua is the heaviest of the three major windowing systems; it has more and more complicated screen elements than either X or Windows. It is about as fast as Windows at drawing individual screen elements (both are faster than X under most driver configurations), but overall, it feels the slowest of any of them at general UI drawing tasks. There are also some operations--like scrolling or resizing complex frames--that are just embarassingly slow.
Overall, I like Aqua for its stability and prettiness (fonts look better on Aqua than any other UI, period), but I can see why its overhead irritates many people, especially those who've heavily customized and optimized an X setup.
That's my $0.02. Hope it helps.

Anyway, someone commented that MacOS X is hard on the apps but cushy on the user, or something like that. Right on. That was one of the Mac's big innovations, the GUI focused on the user. When I am running something like Final Cut Pro, I want every GUI screen gadget running full max. I want every single iota of computing power focused on ME and helping me get through the complex task. This is both the Mac's greatest feature and biggest CPU bottleneck. It's like the olden days of OS 9 before preemptive multitasking, when you held down the mouse, the whole CPU would hang until you let go of the menu. Whenever you were issuing commands, the CPU gave up control to the user. It was a CPU bottleneck, and we LIKED it, it gave the MacOS the immediacy of operation, a feeling of being in control that other OSes lacked. And I think they've translated that well into MacOS X. The system GUI still remains responsive, even when you're running CPU-intensive apps. Apps like Cleaner mpeg2 compression are as CPU-intense as it gets, it can compress 1 minute of DV video in 50 seconds on my midrange CPU. Cleaner is dual processor and Altivec aware, it maxes out both my CPUs, it's as hard a CPU workout as I have found. And it still leaves the system responsive, not locked up and CPU-bound.

The simplicity and clean design of OSX make it easy to hit those buttons without having to pause and concentrate on hitting the correct link unlike in XP where i suffer a considerable amount of arm, neck and hand strain after long hours in front of it. The plain, simple idea of having *all* control panels in one place *without* the Windows mess of myriad unrelated dialog boxes makes it easier to change settings, without first having to find the settings. All programmes have the preferences option in the same place, which is another plus compared to windows. And if I need the detail, power and complexity of Unix the Terminal is a click on the dock away. The Console in WinXP has improved in usability and power (Tab completion, file dragging for paths, output redirection etc) but is still not close to a Unix shell.
As for Applications, Photoshop and illustrator are more sluggish than in XP, except for redraw operations on large bitmaps where Altivec really shines, and I for one tend to work methodically in those programmes and appreciate a programme that doesn't run away from me.

Browsing seems way faster on my home system on a 144 Kbit/second connection with Linux than it does at work on OS X on a T3.
On the other hand, I do have evidence that the Mac is actually slow. E.g., when I start to load a slashdot page at work, I often give up, switch over to the XP machine on the KVM switch, and go load it there, and finish ahead of the Mac. The XP machine is an ancient P2 400 with 384 megs of RAM, the Mac is an ancient B&W G3 300 MHz with about 600 meg of RAM, so the machines are comparable (both pathetic by modern standards, but comparable). So, it actually appears that the Mac is slow at browsing, and IE works in such a way to emphasize that slowness, making it seem unbearably slow.
Also, a lot of apps, and Finder, aren't as threaded as they could be. While IE, for instance, is busy getting that big slashdot page ready to display, the dreaded spinning color-ball shows up, so you can't switch back and view the other pages you were reading.

A lot of people on comp.sys.mac.advocacy have given up on it and switched to Eudora, and report their Macs are nice and fast at mail then.

I just upgraded from an almost constantly crashing Win98 install to WinXP Pro, and over the course of a few weeks so far, I have not had anything but single apps crash a few times...No reboot-requiring freezes whatsoever. Quite a nice break from Win98 freezing before it even finished booting sometimes

i am running an older mac... G4 400mghz running 10.2 with a gig of ram..... i think the pokeyness IS application specific for the most part. i upgraded my Rage128 card to a 7500 when i hopped to 10.2 and noticed it handles the aqua interface a lot better. there are also little things to do to zip up the OS (like under dock prefs switch from "genie" to "scale"), turn off dock magnification, don't use a 10 megapixel picture as your desktop.
obviously it's not as efficient as a very tweaked Linux or BSD box (with fast innards), but as an out of the box OS it's very usable. as always it's better running on newer machines, but i can use it on an older crt iMac G3 300mghz and not bang my head against the table. you might not want to do intense av work on that machine, but for day to day tasks (which iMacs were intended for) it will do just fine.
Re:MacOSX **IS** Slow (Score:3, Interesting)
My understanding is if your windows are being buffered in ram, its slow. If you have an open GL vid card and quartz starts using GL and vram to store the window buffers (its called quartz extreme, right?), much of the slowness disappears. At least until you have tons of windows open
Personally, if 3d/trans desktops are to be the norm in the future, every window will have to be buffered *anyway*, so I think Apple is just taking a performance hit to stay a little ahead of the elegance-curve.
Note to moderators: I might be talking shit, as I'm a former Mac head and now watch from the sidelines. Wait for confirmation from toher folks if you feel like modding my post.

Apple doesn't care very much about European customers. So it's quite hard here to find any store in your neighborhood at all you can have a look at MacOS X in.
(Let alone pricing outside the US, which is just horrible)

That's a brilliant assesment. In fact, Apple probably doesn't care about any of their non-US customers, which is why prices are so unbelievably high. Except in places like Japan, where the prices are nearly identical to those in the States.
Hit www.apple.co.jp and you'll see that a fully loaded iBook costs 231,100 yen. Convert that and you get US$1,897.
A fully loaded iBook from www.apple.com costs US$1,849.
Furthermore, you walk through Shinjuku or Omotesando, and you'll see more shiny Apples than you know what to do with. I've found brand new Macs in South America, too. Even had a repair job on a new powerbook and sat in on an Apple sponsored multimedia conference in Santiago, Chile.
So before you go spouting off about how Apple dicks over their European cutomers, you might want to reconsider. You might want to think about why it is you Europeans love paying all those taxes--all that free healthcare and higher education has got to get paid for somehow. Take a look at those 20% luxury taxes on things like electronics you guys are paying.
When I want socialized medicine, I'm moving to Europe. When you want cheap toys, you might consider a trip to the States.

NeXTStep 5.1 (aka OS X 10.0) was a bit slow. Unoptimized, but important to get out the door so developers would get some pressure to compile for OSX which they had ignored for the 4 month Beta period. This strategy of pushing developers was successful with the 128kb Mac that forced developers to use the consistent, common ROM routines rather than writing their own UI as DOS had taught them to do.
10.1 involved lots of work to optimize libraries and make it a bit more than the "Hey, the OS built!" level of quality.
10.2 (NeXTStep 6.1 more or less) is a fairly major step forward and is brisk enough for me. But then, I run a bunch of terminals, iCab or Opera (or mozilla), occasional PhotoShop and that's most of it.
The kernel is finally enabled with debuging so ktrace works. I just wish the thing were OpenSource. Darwin isn't enough. Oh, and real IPv6 support (more than just "ping6") would be useful. NetBSD runs fine, but it would be nice to cvsup from apple, rebuild and go.
Hell, it would be nice to cvsup from RedHat or Suse, run "make build" and go.
If I need speed, I can log into the 8 way SGI at work (from the Mac) and do stuff there.
But looking at the 166MHz BSD SPARC 20 that's the home server, I'm not sure why I need more than the power suckage and heat that 500MHz gives me except for gaming.
I'd rather save the cash for a new machine and get a T1 or more RAM in the current machines.
