Start by running 'ab' against your server. The 'ab' (Apache Bench) tool 
allows you to find out just how fast or slow your server really is. 
Second, make sure you **do not** have 'HostnameLookups On' in your 
configuration. Turning on hostname lookups is the surest way to make 
your server slow because it does a reverse DNS lookup for each access 
(which can take several seconds depending on where the surfer is coming 
from).

Third, quit putting yahoo groups in the Cc line of your emails. Anyone 
not subscribed to them gets a bounce when they reply to you.
