this isn't really a solution, because linux development will outpace you,
but have you tried building a really tight kernel? for desktop machines,
i've gotten noticable performance gains by building a moduleless kernel
with only the minimum needed functionality. i built custom kernels for
(unnamed registrar) and we got +10% packet throughput on linux 2.4
running an (unnamed nameserver) for (unnamed tlds).
i think there are some kernel threads that you may be able to eliminate
with a different kernel. i don't know if you need 'em though.
