Finally! I was waiting for somebody to do such a comparison. Will you be
able to publish the results and the methology you used?

Good to hear :)

That should be a given, if you want to do a fair comparison. Did you do
any kernel tweaking? Or did you try to keep them as "out-of-the-box" as
possible?

Both SUSE and Red Hat apply quite a number of patches to the Linux
Kernel - none of them can really be considered a "vanilla" kernel. Take
a look at the patches that are included in the Kernel source RPMs. It
seems like SUSE did a better job of enhancing the Kernel. One assumption
would be that they have made changes to the VM and scheduling. After
all, Andrea Arcangeli, who is one of the kernel VM hackers, works for
SUSE...

I have always assumed that the SUSE kernel would outperform the one used
by Red Hat. I would love to see some facts that actually proof this.

Bye,
LenZ
