** Description changed: I noticed bad performance regression with xorg-server 1.5.2 (intrepid) against 1.4 (hardy). For the detailed report see here: http://lists.freedesktop.org/archives/xorg/2008-October/039277.html - 1) Reading the suggestions from the thread appears that this patch could fix the performance problem: + There are two known problems: + + 1) Patch to fix slow EXA in 1.5.2: + http://lists.freedesktop.org/archives/xorg/2008-October/039405.html + + 2) Reading the suggestions from the thread at + http://lists.freedesktop.org/archives/xorg/2008-October/039277.html + this backported patch from 1.6 should fix the performance regression in 1.5: http://cgit.freedesktop.org/xorg/xserver/commit/?h=server-1.5-branch&id=8ef37c194fa08d3911095299413a42a01162b078 - The fix was applied to the 1.5 branch but was later reverted.
