Monitoring Eclipse performance: what is Eclipse doing?

Question

Lately I have been experiencing Eclipse Galileo (3.5) slowing down under Java 1.5b12 OR Java 1.6b10, every 10 to 15 minutes for about 30 seconds, it hits a 90-95% CPU load. The progress view shows nothing, however.

I'm suspecting a plugin is causing issues, but what I'd need is some tool or plugin to monitor Eclipse for what it is doing during those spikes.

Does such a plugin or tool exist?

Edit #1: added details about Eclipse version and Java version (d'uh, sorry)

Answer 1

If you have the right eclipse.ini, you can then monitor an eclipse session with JConsole.

• eclipse.ini for 3.4.2
• eclipse.ini for 3.5

I had the same issue with old eclipse3.4 or 3.4.1 installation. In both cases, switching to eclipse3.5 with the latest JDK solved the problem.
