I am not aware of anyone having profiled Cocoon in the manner you are
proposing. The results would be most welcome.
We saw a huge benefit when we switched from Xalan to XSLTC. And you
always see a huge performance loss if you exceed the pool size of your
components.
JMX instrumentation has not been added. However, I understand that there
are commercial tools that can add instrumentation in an aop manner.

Hello,
I'm working on performances for the application of a client. And it's
a little difficult to know which direction to take.
I would like to define performance test guidelines that would permit
to every cocoon developer to test its application and drive easily its
own test. I read almost all the thread and documentation about
performances, but I just found a few tips (and it's already a good
thing). What I want is to analyze the cocoon code, and in more
details, the cocoon portal block.
To conclude, and because it's a reccurent question, I will create a
wiki with all the information I will get here.
Is there anybody that has already profiled Cocoon with JProfiler and
JProbe. Are the results interesting ? What are the tools' limits ?
Finally, what I'm looking for is a tool that will show me how many
times a method is called, and how much it consumed. In a very naive
approach, a simple log in each method would be helpful. A few times
ago, somebody talked about AOP, have you heard about this thread ?
I heard about JMX too, when people were thinking about removing
instrumentation from 2.2. Has it been developed ?
Thanks for all the tips.
