Dual Processor Server Or Not?
 

I'm looking to get yet another server and was wondering what the difference in speed would be with lets say a dual P3 1ghz as compared to a P4 2.6 ghz?

Anyone know?

Depends on what kind of applications you're going to be running on the machine. If you're just serving a buncha of http requests then you might go for the dual CPU but if you're running an intensive process, like a mysqld server, then try to stick to a single processor.

The other consideration is your OS, linux has better support for SMP than a FreeBSD machine might have (this will change soon).
