Well, as I stated, I use 2.7.2p, and I have experienced no problems at all.
I usually optimize the kernel only at O3 however, because after playing with
the benchmarks O3 and O4 are about the same, but O6 makes some things faster
while some other things get slower.
I finally got my Byte benchmark up to a 22.0 (by unsetting all environment
variables). But even with out doing that, I was around a 21.6 to 21.8. For
a P133 this is pretty good, especially with an EIDE interface and 1k ext2
fs blocks. I compiled the benchmark binaries in ELF as well, because my
system is almost completely ELF. Aout is supposedly even faster.
I haven't installed the sched.c patch because I would like to
get readprofile to work on /proc/profile, but I can't get it to work.
Any help would be much appreciated, or another way to profile the kernel
that I haven't heard about.
Thanks!
