[SATLUG] Ubuntu x86 vs x86_64 Performance

[Daniel J. Givens]

I am amazed at what I have recently found. I wish I had hard numbers on this,
but Ubuntu performs remarkably better as x86 than x86_64. Same system, same
specs and everything is better. Memory utilization for the same applications is
incredibly lower. The Nvidia drivers render smoother AIGLX graphics. VMWare runs
smoother. I really feel silly for using x86_64 for at least six months now.

The servers that I'm running x86_64 Ubuntu on seem to be doing just fine, so I
wonder if it isn't something to do with something in the graphical side that is
a problem. Has anyone else seen similar results? Thoughts or speculations?
