At the Apple developers program it has been mentioned Lion GM is way slower when you have Intel HD3000 chipsets (every new MBP).
I may/can not post the whole thread but here is a snipped:
10.6.8
User Interface Elements 399.27 1.83 Krefresh/sec
10.7 (GM):
User Interface Elements 81.64 374.70 refresh/sec
That makes Lion about 5 times slower with Intel HD3000 chipset.
Unbelievable but true. :-/
