I am currently tasked to look at memory profiling/load testing tools. From looking a forums it seems that JProbe and optimizeIt are the two most popular as far as memory/bottleneck monitoring tools. I'm sure many of you guys have looked at these products. What pros and cons are there with these products or is there a better open source route.

thanks

Take a look at http://www.devstream.com. JView 2004 is a very low-overhead J2EE Production Performance Monitor and profiler, allowing for deep-level diagnostics to identify and resovle performance issues (no memory profiling though). Good luck!

I have used Jprobe's Profiler and Memory Debugger. Both are excellent tools which help identify inefficient methods, and memory leaks. Quest has started providing a "freeware" version of Profiler. Both tools require high-end machines and must be properly configured to be effective. Also, user training is a must. You can also use Jinsight (from IBM) which is free. I liked its graphical call tree representation better than Jprobe which tends to become hard to follow for complex enterprise applications. Good Luck. Kamyar

We switched from OptimizeIT to JProbe some time ago for the following reasons:
- OptimizeIT was not as stable enough for big applications, occasional errors occured
- JProbe CPU profiler is easier to navigate

Disadvantages of JProbe:
- more complex to setup
- more expensive

Of course there are tons of other tools free to expensive, that could be used.

Kind regards,
