10.1 | 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. | ||
| 9 | |||
| 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. | ||

10.1 | 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. |

10.1 | 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]] |
| |
6.1 | 25 | There is a lot of good information there. |

| 29 | (As of March 2007 the J-Sprint link above does not seem to work - the software may not be available anymore) | ||
| 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. | ||
