![]() And then there's the amazing AltiVec (which Apple call the "Velocity Engine", if you see these terms they refer to the same thing). 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). So the Kernel isn't actually slow, it compares well with other BSDs and Linux. 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. Mac OS X isn't actually slow but has a lot of technologies that have got a bad rap (though they didn't always deserve them).
