The fact that it seems to fluctuate pretty wildly makes me wonder
how stable the numbers are.

I can't resist myself from bragging. The high point in the fluctuation
might be because someone is working hard trying to make 2.6 kernel run
faster. Hint hint hint ..... ;-)


Heh. How do you explain the low-point? If there's somebody out there working hard on making it run slower, I want to whack the guy ;)


If it is doing a lot of mapping/unmapping (or fork/exit), then that
might explain why 2.6.11 is worse.

Fortunately there are more patches to improve this on the way.

Kernel profiles would be useful if possible.
