  4. Hello,
  5.  
  6. I thought Linux users might be interested in the following benchmarking 
  7. that I did on my system.  I ran speedometer under the standard 
  8. XFree3.1.2, then under the exact same configuration I ran it under 
  9. Xinside's Xaccel...  Here's what I found:

  50. What I thought was particularly interesting was that calculations seem to 
  51. actually speed up with AccelX also.  Why is this?  I was expecting those 
  52. to stay constant, but only have the video-related tests to improve...  
  53. Can anyone explain this odd phenomena?
