RE: Tools for benchmarking profiling Tomcat
Thanks Yoav, I have tried OptimizeIt which does not seem to have the same problem with idle IO time as JProfiler, and so I got much different ( and better ) results. Some tech staff at ej-technologies, told me that the next release of JProfiler in a few months will have a seperate IO state that will take care of this problem.

I have not gotten jmeter to support mutually authenticated SSL. Is this possible? jmeter -Tim Steph Richardson wrote: I guess this is more of a generic http server question than a tomcat one, but I'm looking for recommended toolset(s) to use in benchmarking the performace of our tomcat based webapps.

RE: Tools for benchmarking profiling Tomcat
Second half of this question is what is a good profiler to use with Tomcat ? I am currently using JProfiler ( http://www.ej-technologies.com/products/jprofiler/overview.html ) which plugs plays really easily with my current Tomcat install, BUT it's major problem is that it includes time that threads spend idly listening on sockets. So when trying to identify performance hotspots in a server app like tomcat, it becomes very difficult to get a good view of what percentage of time is spent where. I have seen JProf ( http://starship.python.net/crew/garyp/jProf.html ) but I am scared by the use of the terms C++ JFC on the intro page. Any other suggestions - especially for something that will work well with Tomcat understands how to treat time spent in the IO libs.
