There's not much more to say. Tiger is faster than Panther, and you'll notice. The GPU-powered graphics technologies play less of a role in day-to-day performance increases than you might expect.Is it just code optimization?
Every single major revision of Mac OS X has been faster than its predecessors when running on identical hardware. Jumping several major revisions is practically like getting a new machine. It's impressive, and unprecedented.On interface responsiveness:
Of course, the pessimistic angle is that Mac OS X's performance was so abysmal in version 10.0 that it had nowhere to go but up. Like System 7 and Mac OS 8 before it, Mac OS X is indeed perceptibly slower on the same hardware than its distant predecessor, Mac OS 9.
But that's really reaching. At a certain point, you simply have to accept that Apple is doing a heck of a lot more than patching up grossly inefficient code rushed out to make the 10.0 release. It's time to give credit where credit is due. Apple keeps making Mac OS X faster, and it rules.
Tiger takes the biggest leap yet in this area, and that's saying something. Improved window resizing responsiveness in particular is immediately noticeable in Tiger. It's still not perfect, but it's a big improvement. Compared to Jaguar or earlier it's like night and day. Scrolling is also a bit snappier, although this is not as noticeable, perhaps because scrolling was already pretty good in Panther (in most apps, anyway).On Quartz 2D, he notes that software-only line-drawing has sped up by a factor of ten, making it five times as fast as Quickdraw. Quartz 2D Extreme, with its hardware acceleration, is 8x faster at line-drawing that regular Quartz 2D now is and 3x faster at text. Extreme is turned off by default for now, probably to work out some last-minute bugs. But what that means is 10.4.1 is going to give yet another speed boost once Apple pulls the Extreme switch.
It would be easy to attribute all of these improvements to Quartz 2D Extreme. It'd also be wrong. Disabling Quartz 2D Extreme (using the Quartz Debug application that's part of the free developers tools bundled with Tiger) has little perceptible effect on window resizing, in particular, for most applications. What this means is that not all UI performance is gated by drawing speed.
What, is there something wrong with typing in the word processor and then watching as your words appear seconds later?I still get that on my Apple eMate, and it's my favorite way to write. I just try not to look as I type.

I'm really pleased with Tiger. I expected just another BS annual Apple upgrade, but it's impressive, even beyond Spotlight. OS X has become an orgy of OpenGL and XML.
ArsTechnica has a lengthy, geeky review that's a lot more informative than Apple's marketing-speak.
Dashboard is way more useful than I expected, not to mention how FAST it pops up.
