Comment 22 for bug 288650

I can confirm that Java: 1.6.0_12-ea; Java HotSpot(TM) Client VM 11.2-b01 fixes the problem for me, netbeans runs fluently with the default xorg.conf (no Option "AccelMethod" "XAA")

This is a subjective test but it is very clear that the performance is more or less back to normal. Would you like me to run some kind of benchmark?
