If you're referring to the currently offered Gentoo kernel, I upgraded
to it from the vanilla sources three days ago. An upgrade is exactly
what it was: the preemptive patch (and probably a few of the others) has
made my workstation/server system significantly more responsive. Perhaps
you're not noticing a speed boost because you turned that option off?

There are also numerous security enhancements, most notably kernel-based
encryption (including IPSec) and improvements to IPChains. Gentoo bills
their kernel as "security and speed enhanced" in their install script,
and having installed it with their options selected, I've found that it
meets my expectations in those areas.

I agree that if RedHat has a patch that makes part of the kernel faster,
it would be useful to have it integrated into Gentoo's kernel. Better,
they ought to submit it as a patch to Linus' tree, so everybody using
that tree as their springboard will benefit. If neither of those things
has happened, though, there's likely a good reason for it.
