Howdy,
I would use JMeter first, if you're just looking for performance
numbers, i.e. time to serve that page. JMeter is ideally suited for
that. JProbe and OptimizeIt are great, but they do more than you need
in this case and they WILL skew performance significantly.
As an aside, make sure you have all log4j Logger#debug statements
enclosed in if(logger.isDebugEnabled()) { ... } clauses -- that's an
order of magnitude or so runtime performance improvement.
