1 A profiler is a development tool that lets you examine memory useage and other bottlenecks in your app.

5 I've tried some of them.

7 For the big problems jprofiler is great. The docs are useful, the interface is good and the performance is okay.
8 I prefer jMechanic. It's small, free and works together with WOLips. Just some clicks to set it up.

10 I don't remember much about the others. Some of them don't run under MacOSX and it can take a lot of time to find how to use them together with WO.

19 If profiling on Windows is an option, you might also want to look at jSprint:

22 It is shareware, US$50. I've used it and was satisfied with it. It seems like a good deal for the price. I've not (yet) used jMechanic, so I can't compare the two.

24 Before you buy anything or try anything you would be well advised to spend a couple of hours at the above Java Performance Tuning site reading up on it: [[http://www.javaperformancetuning.com/index.shtml]]
25 There is a lot of good information there.

30 None of the tools on this page appear to work with WebObjects 4.5.1 on Windows.

34 I use [[JProfiler>>http://www.ej-technologies.com/products/jprofiler/overview.html]] from [[ej-technologies>>http://www.ej-technologies.com]]. It works as well as any of the other big named profilers, and it has explicit support for WebObjects. It is, however, not free like some of the other suggestions.
