Description of problem:
it would be nice if redhat offered a kernel that was patched and compiled
specifically for desktop use. it would make a real difference in perceived speed
for the desktop user.
i don't mean replacing the kernel, but offering it as an alternative like the
smp kernel and others
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. compile new kernel with patches
2. watch speed difference
RHL9 is already intended to be tuned for desktop use. What kind of patches did
you have in mind ?
(the low latency patchkit is already included for example)
is the low latency patch compiled into the kernel, i know it's included in the
sources, but i thought the default kernel was compiled without it
i also like the preemptible patch a lot
the low latency patches are compiled into all kernels.
I'm not going to merge the preemptable patches; they provide little gain on top
of lowlat (we've done the measurements) and in addition are not feasible on 2.4
kernels, it just changes too much of the fundamental assumptions of the code. In
2.5 kernels all those are (still) getting fixed, but in 2.4 it's just not doable.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
