Tiger is noticeably faster in the GUI compared with Panther. Scrolling and resizing windows, dock zoom, minimising windows etc all works better under 10.4 than 10.3 (and the cool looking liquid ripple effect when dragging widgets is smooth as silk).

Funnily enough, however, Exposé window zooming and resizing is much faster on 10.3 than 10.4. Taking as few as 4 windows or as many as 20, shows a more fluid effect on Panther (30-40%, I would guess). I cloned the HD to 2 seperate partitions on an external drive, and installed 10.4 on one and booted between the 2. All settings and hardware are identical. I have also tried it on 3 different machines:

PB 17" 1.67/1Gb/128Mb Radeon 9700M
PM Dual 1.8GHz/1Gb/64Mb GeForce FX5200
iMac 17" 1.8GHz/1Gb/64Mb GeForce FX5200U

Exact same result. Panther scales few or many windows faster and more smoothly than Tiger does. It's almost like the processor has been turned from High to Automatic, except this is not the case.

I'd be interested to hear from anyone else who has also noticed this.

I've found the same thing. 10.3.9 was perhaps the smoothest I've ever seen Expose running, and it's the least smooth under Tiger. Using the shift-key trick, you see that once windows get to a certain size (smaller) there's some noticeable chunkiness. It's weird. Functionality is the same of course, but it doesn't feel as satisfying.
