Following up on this I'm also looking into buying some servers and have
the almost the same scenario, a MySQL DB together with apache with
mod_perl and embperl, (alot of SQL and dynamic content). Would we be
better off with:

Dual Xeon, 2.4 GHZ with 2GB of RAM or Xeon 3.0 GHZ with 2GB of RAM
RAID-1 on three disks or RAID-5 on three disks.

Will the difference between 2.4 and 3.0 really do that much ? Isn't the
SMP system better.

Kind Regards,
Stefan Cars
