Slow JSP Compilation in Debug Mode

[fuseboy]

I'm running JBoss-Jetty in debug mode under IDEA and everything runs smoothly except for JSP compilation, which is appallingly slow, to the point that even on my decently fast machine using our web app in debug mode is too slow to be useful.

Is there some setting that I can change that would improve this, or is it some kind of interaction between the VM's debug mode and the compiler which I can't do anything about?

I'm using the JDK 1.3.1_01, JBoss-2.4.3_Jetty-3.1.3 under Windows 2000.

I see the same thing on JBoss3.0.1rc1 and tomcat. Debugging through idea is VERY slow, much slower than 2.4.x
