How Snow Leopard Cut ObjC Launch Time In Half 158
MBCook writes "Greg Parker has an excellent technical article on his blog about the changes to the dynamic linker (dyld) for Objective-C that Snow Leopard uses to cut launch time in half and cut about 1/2 MB of memory per application. 'In theory, a shared library could be different every time your program is run. In practice, you get the same version of the shared libraries almost every time you run, and so does every other process on the system. The system takes advantage of this by building the dyld shared cache. The shared cache contains a copy of many system libraries, with most of dyld's linking and loading work done in advance. Every process can then share that shared cache, saving memory and launch time.' He also has a post on the new thread-local garbage collection that Snow Leopard uses for Objective-C."

You've had enough of fucking, and would like more Snow Leopard stories? Each to his own, I guess.

Well okay then, Apple were the ones who "popularised" it! ("Well I hadn't heard about Superfetch, but I heard about Apple doing it first, therefore, Apple did it first")
Or um ... they "integrated" it better. Yeah, that's it.

Hey, it makes a refreshing change from the daily "Do XYZ On Your Iphone" stories! I'm love the variation today here on Apple- er Slashdot.

dyld - noun. A reminder that regardless of age, you'll always have an adolescent sense of humor.
