dual / quad core processors

mnauta · 11-05-2008, 02:08 PM

I am currently run Scalix email server on FC7 / Proliant ML370 G4 / dual core Xenon 3.1 Ghz processor 3 Gig mem.

I have very high CPU and IO wait issues on the server. Will I benifit to upgrade to 2 quad core processors?? Does the Fedora C7 architecture benefit from 2 dual core or quad core processors?

Thanks

If you are seeing CPU queuing on a 2-way, more engines will help. Almost certainly. Fedora can handle any number of CPUs/cores you are likely to purchase.
iowait is a different issue altogether - throwing more workload (from more/faster CPUs) at the environment may (will) exacerbate the problem. Spend some money there as well.

Maybe think about 64-bit and (lots) more memory whilst you're spending the boss' dollars ...
