Reasons for slow applikation startup?

Mon Nov 1 21:23:00 GMT 2004

First of all thanks a lot for your reply!
The funny thing is that the trial version of a good commercial profiler 
told me that most time is spent somewhere else, of course when profiled 
it ran on Sun-Hotspot-Client-VM.
So there are two possibilities: gprof lies or GCJ performs really bad on 
some SWT code (1/1000x of hotspot).
I think gprof lies - are there any other, better free profilers that 
work well together with GCJ (maybe without even recompiling it?).
Thanks in advance, lg Clemens
