Subject: Ruby performance degraded on custom kernel

Hello list,

I have a rather odd question regarding ruby's performance on a system
with a vanilla kernel from kernel.org version 2.6.18.1.

I have two identical systems.
One system has a minimal debian etch system installed which I use as a
host.
The other system is using a vanilla kernel from kernel.org.

The ruby installed is 1.8.5 patchlevel 2.

The ruby interpreter is 50% slower on the vanilla kernel system. Is also
uses a lot more CPU.

So I wonder if there are any kernel parameters that you know about that
could affect the performance of the ruby interpreter?

Any other ideas would be greatly appreciated.

Cheers,
Henrik
