Run a DDoS-style (but not legitimate DDoS attack) load-balance
simulator against your site and see where the bottlenecks lie. The
biggest problems are general filesystem writes (including sessions)
and database queries.
If you have multiple servers from which you can run test scripts,
do that (preferrably from various networks). If not, do what you can
with what you have. Make sure your testing system simulates the
traffic in the manner you expect (clicking links before the page fully
loads, closing the connection and immediately refreshing it, et
cetera).
Tools of the trade:
top/htop (for general system process watching)
mtop (for MySQL)
mod-top (for PHP process watching)
apachetop (for Apache)
And invaluable things to remember with regard to MySQL:
The 'log-slow-queries' option
The SQL statement: SHOW PROCESSLIST;
