JBoss plugin extremely slow when debugging

Web app startup time is 4+ mins (debug) vs. 20s (run). It also seems that CPU is taxed heavily while running via debug.

My machine specs:
Mac 10.6.8
7GB memory
4 core CPU
IntelliJ IDEA 10.5.1 (new release)

Any ideas why or how I can troubleshoot?

Thanks,
Shane
