Alex Balashov wrote a fantastic article on this:


Lots of good tips and explanations in there... with a tl/dr; being 
there's no straight forward answer to reaping maximum benefit.

For example, you're using DB... which many of us do. Are you using 
HTABLE to cache information that can be cached? Perhaps instead of 
running a query on every hit, you can run it every 5 min... or cache the 
password and save some lookups on authentication, etc.

Anyway, lots of ways of approaching this and the article above is a 
great place to start.
