Hi, I'm using the Grinder. It's free, and very flexible. The advantage over Optimizeit, is that you can test any server with the Grinder, without having to launch it in a special mode. In order to use Optimize It, you have to modify the startup script of your application server, for example, in order to monitor it. Val�ry
We maintain a list of performance related resources at the JavaPerformanceTuning.com resources page. In particular look at the two sections Free Profiling Tools Not Free Profiling Tools. Avi, if people read past postings, this forum would be probably be much quieter. Valery, The Grinder is a load testing tool, and I think the original question related to tools which can identify performance problems within the code. Of course, I could be wrong, in which case you'll find the other tools (inlcuing The Grinder) also listed in the previously mentioned resources page. Finally, the tool reports page gives actual examples of using some of the tools listed in the resource page. --Jack Shirazi JavaPerformanceTuning.com
IBM's WebSphere Studio Application Developer (WSAD) 4.0 and 5.0 have a so-called "Profiling Perspective", which is really an embedded profiler. If you remember Jinsight from IBM Research, it is it's commercial successor. Haven't had experience with other commercial (or free for that matter) profiling tools, but on an absolute basis I am satisfied with WSAD's capabilities. If what you are looking for instead is a load testing tool, then Mercury Interactive's LoadRunner is the de facto standard. Very good, but expensive.

So what are you saying, then? Is this a good thing, or a bad thing (in your opinion)? Cheers, Avi.

It's good for people that read past postings and don't like to see questions repeated. It's bad for people who like to see traffic on the forum. It all depends on your perspective. Myself, I don't care either way. --Jack Shirazi JavaPerformanceTuning.com
