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.
