    I have a program that does a bunch of initialization stuff before it starts into it's main event loop.  This initialization usually takes about 1 second.  I tried running this program in debug mode without any breakpoints or watches, just starting it up.   What normally takes 1 second took over four hours to run.   The main java process reports 253 minutes of CPU time.  During this time top/vmstat/iostat all reported 100 user time, no IO and no virtual memory.

    This is an a Fedora 1 intel box with a 2.8ghz pentium and 2gb of memory, etc, etc, etc.

    Any ideas on why I would see such a huge difference in performance?
