Bug Description
I noticed bad performance regression with xorg-server 1.5.2 (intrepid) against 1.4 (hardy). For the detailed report see here:
http://
There are two known problems:
1) EXA: Avoid excessive syncing in PutImage
Patch to fix slow EXA in 1.5.2:
http://
the fix was included in 1.5.3.
Test package of xorg-server 1.5.3~git-

See comment #6 (https:/
2) Array-index based devPrivates implementation
Reading the suggestions from the thread at
http://
this backported patch from 1.6 should fix the performance regression in 1.5:
http://
This fix was applied to the 1.5 branch but was later reverted. It appears that this fix breaks the ABI (so it's not for intrepid):
