Thanks for that. I did read through those mailings both at the time when they were posted, and yesterday when I was searching the archive for hints and tips. My selfish interest was in finding ways of profiling some of our own code with works on top of Cocoon, but the principles of profiling Cocoon and related code should be the same, so I hoped it was appropriate to ask for any hints and tips.Vadim Gritsenko wrote:I got a 30-days evaluation license of OptimizeIt and run it against Cocoon a while ago and I found out that cocoon (talking about CVS HEAD) is pretty well optimized already, expecially for memory consumption over requests.Stuart Roebuck wrote:I need to do some code optimization / profiling on Cocoon and some additional Cocoon libraries we've built. This raises an issue which I thought might be of general interest, and hoped might open up some new avenues of profiling discovery!...
If there was an open source based approach to profiling Cocoon code, I would be happy to write up the process to aid others in the future.

OptimizeIt costs money, but I've got a license... I *will* profile Cocoon sometime again, and would do it sooner, but my unfortunate schedule moves this event to the 1Q or 2Q of the next year.
Look into the mail archives for that message since I sent a report here to the list.
From my point of view, whenever I have been writing code for Cocoon I have done a lot of unit testing on components utilizing 'Mock' classes, and I have done more broad brush system performance testing, but I have always shirked away from full blown profiling because attempts at it have met with failure or masses of incomprehensible or useless data.
If I could find a simple way of profiling code 'in context' it might help to improve the performance of our code.
So far, jProfiler (which offers an 8 day trial) has proven very easy and effective and seems to run fine on Java 1.4.1 on Mac OS X. Now I just have to find some way of paying for it!
