I don't know where to start on this, so this is a very broad question.

We have a large project (5000+ java files) with a lot of dependencies on external libraries (~100 jar files). When making any changes to this project, or even just viewing code in this project, Eclipse frequently hangs for 30s to a few minutes. The program becomes unresponsive and consumes 50% CPU (on a 2 core machine) for the duration of the hang. This issue does not happen for any of our smaller projects, only on this monster of a project.

The .log file in the workspace metadata folder does not provide any clues to what it is doing during this period. I am currently running Juno SR1 on Windows XP, but this problem also existed in Juno and Galileo.

Does anyone know how to resolve or further diagnose this issue?
