Title:
[i965gme] severe 2D performance degradation after upgrade to Maverick
Status in “xserver-xorg-video-intel” package in Ubuntu:
Fix Released
Bug description:
Binary package hint: xorg
I recently upgraded to Maverick and since then the graphics performance of
certain 2D programs severely degraded. Especially programs that use wxMathplot
with real-time plot updates are affected and show very high CPU on the xorg
process and much lower responsiveness of the application.
When I run the same program within Xephyr, the CPU load is much less, also
when I run it under ms-windows in VirtualBox. I have tried the stable ppa
update for xorg-intel, but this didn't make much difference.
I have done performance analysis with oprofile (on my own applications
that uses 10 wxMathplot plots) and found that the the kernel (55%) and
libdrm_intel (15%) are eating most of the CPU time.
I created a slightly modified version of sample3 of wxMathplot that
shows the CPU impact of 2D operations. Directly under X, CPU usage is
as follows: 53% for Xorg and 14% for mpSample3. Under Xephyr, CPU
usage is 10% for xorg, 15% for mpSample3 and 11% for Xephyr. I'll
attach the source of this modified sample, and if required more of the
oprofile log.
