low latency patch for Red Hat 9 kernel

Hi all,

I am using a Red Hat 9 distro since a few month (and kinda like it).

I have the "stock" kernel, which is 2.4.20-8 it seems.

I'd like to install that famous "low latency" kernel patch... but I don't
know which patch to apply

I read about "test5" and "test6" low latency patch, and really don't
know what to look for

If I dowload the kernel 2.4.20-20 from Red Hat, will this patch already
be applied to it ? (how can I check ?)

Are these low latency patches compatible with the NPTL (Native Posix
Threads) that Red Hat 9 uses by default (which was not supposed to
be backported to 2.4 ?) ?

I like Linux a lot, but I am getting some strange "two to three seconds delay"
under some conditions... And people having the same problem said it
disappeared when they applied this low latency patch...

I know how to recompile a kernel, but I don't know which patch to
apply to the sources, nor if it compatible with the custom Red Hat 2.4 NPTL
kernel...

Thanks in advance for any help,

Jean
