I just finished upgrading to Tiger (I did the "upgrade" option from 10.3.9), and so far all is running at least as well or better except for ONE thing:
Expose is slow, but only on the F9 (display all windows) event. All other expose events are nice and fast. Spotlight is done indexing, and I upgraded to 10.4.1, and the issue still exists.
I have a 17" 1.67 PB with the 512 MB RAM and 128 MB VRAM.
Anyone else experience this?
