Profiling Cocoon for cheapskates

[Stuart Roebuck]

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.

* We're on a budget and can't afford to pay $400+ per seat for a commercial profiling tool.

* java -Xrunhprof appears to die during final output when given the significant task of profiling our code in Cocoon in Tomcat in Java, etc.. It's also fairly slow, but we would live with that if it worked.

x Fortunately... x

* We're developing on Mac OS X - but that might not help us in finding low budget profiling tools! :-)

x----------------x
x Resources... x
x----------------x

* A good starting point for profiling resources is Jack Shirazi's Java Performance Tuning web site:
<http://www.javaperformancetuning.com/>
which has a list of free tools:
<http://www.javaperformancetuning.com/ resources.shtml#ProfilingToolsFree>
My initial attempts (though brief) to get a selection of these running on Mac OS X has been unsuccessful.

x Questions... x
x----------------x

1. Does anyone have any experience of any free profiling tools other than the built in JDK tools?

2. Is there a way of turning the built in profiling facilities on and off with code (in order to selectively profile code and avoid overloading the built in profiling facilities). This used to be possible in Java 1.1. <-- little known useless fact!

3. Any other useful Cocoon library profiling suggestions?


Stuart.
