Load Testing / Profiling

Hello everyone,

Our website based on cocoon grew quite big.  And I've
noticed that it slows down quite a bit over the time
of usage.  So I would like to know what what would be
the best way to find possible leaks in cocoon.  How to
load test it properly and profile it.  Any suggestions
would be very appressiated.

Configuration:  Linux, Cocoon 2.15, Tomcat 5.0.19

Thank you,

Anton

I'd create a lot of requests, for example with ab [1], to try and find 
which ones cause an increase in memory usage.

Not only "normal" user requests, but also requests to 
intermediate/internal pipelines (on a test system with less 
restrictions than usual maybe).

And a *lot* of requests, working on one URL at a time until you find 
one which shows the same symptoms. Stress the beast until it cries ;-)

Hope this helps,
-Bertrand
