Title:
Performance drop after suspend/resume cycle
Status in linux package in Ubuntu:
Invalid
Status in nvidia-graphics-drivers package in Ubuntu:
Invalid
Bug description:
A slight but noticable drop in graphics performance can be observed
after a single suspend/resume cycle in the latest -proposed kernel in
Ubuntu Lucid (2.6.32-26). I haven't tested if the problem is more
general, or if it only applies to graphics operations.
glxgears numbers before first suspend:
18494 frames in 5.0 seconds
16493 frames in 5.0 seconds
16521 frames in 5.0 seconds
17073 frames in 5.0 seconds
18495 frames in 5.0 seconds
glxgears again under exactly same conditions after a single suspend/resume:
15517 frames in 5.0 seconds
15672 frames in 5.0 seconds
15684 frames in 5.0 seconds
15687 frames in 5.0 seconds
15680 frames in 5.0 seconds
I know glxgears isn't a proper benchmarking tool, but the point here
is the *relative* decrease in performance. The performance drop is
also noticable when for instance browsing web pages in Firefox.
This is a regression, kernel 2.6.32-25 in Lucid does *not* have this
problem.
Using nvida driver 195.36.24.
