Performance of standard kernel versus re-built kernel

Performance of standard kernel versus re-built kernel

I run RHEL 3.0 ES on a Dual Xeon 3.06 Ghz, with 2 Gb RAM.

My experience from other (Pentium III and older Xeon) systems with
Redhat Linux 7.x was that self-compiled kernels had substantial better
application performance compared to the binary kernels coming from Redhat.

I wonder whether I should also build my own kernel for RHEL 3, and how
much performance I would gain by
- optimization for processor family
- turning off undesired kernel modules
- going to the 4Gb model instead of the default 64Gb RAM model

I am aware that Redhat support would be tricky with a self-compiled
kernel, but I presume that in case of problems I could boot back into
the released kernel, and if a problem reproduces there, stick to that
configuration while dealing with support.

Alois
