The low-latency and preemptible patches are not meant for performance
gains, but for responsiveness, and are not designed to be used in servers,
only in workstations/desktops.

2.4.18 does come with a improved VM, what could justify the performance
increase. As could an update on the compiler (I've being using gcc 3.1 in
my redhat 7.2).

But I can't recomend the beta to anyone, we had problems with one
dual pentium iii server, causing random corruption on
/usr/include/*.h and a lock up.
