6.5 RC1 : Why Is The Debugger So Incredibly Slow?

[willfarnaby]

It takes several minutes (3, 4 or perhaps even 5) for the (Java) debugger to start and become ready for user input. I've noticed this for some time now, and it's so bad that I basically never use the debugger.

I cannot believe that others do not experience this lack of performance... comments?

[I have a dual-core with 2 GB RAM, lots of disk space, XP Pro, no other app hogging the CPU, etc.]

I still have this problem with the NetBeans 6.5 Java Debugger: it takes 5, 6, 7 or 8 minutes - you get the idea - to start and become ready for user input through its GUI. I looked through my ZoneAlarm logs, but I don't see anything of interest there. (Someone on nabble suggested that the debugger may be timing out on some (local, I presume, since I'm just trying to debug on my own workstation) TCP/IP connection.)

I didn't notice until today that the debugger is very slow in NB 6.5.  
I'm using it to debug a web app on GlassFish V2.  I sometimes have to
wait a minute for the UI to become responsive and there is very high CPU
usage while debugging.

Hi,

    it seems you've run into
http://www.netbeans.org/issues/show_bug.cgi?id=151293.
Anyway, to be sure, could you please file new issue against debugger and
generate thread dumps?

Thanks,
-Peter
