Comment 3 Roman Ondruska 2005-05-12 13:32:48 UTC 
We will discuss it. Let me note that JDWP traffic strongly depends on selected
debugger view.
Comment 4 Martin Entlicher 2007-03-12 11:18:34 UTC 
This looks more like a defect then feature. We will look at this in bugfixing
period.
Karel, do you have the tool which generated these reports? Can you send it to me
offline, or provide a link here? Thanks.
Comment 5 _ kherink 2007-08-22 07:19:35 UTC 
i am now able to open source the GUI based JDWP proxy/analyzer which i wrote to help me track down debugger problems. is
it possible to add it into NetBeans CVS under the debugger module?
Comment 6 Martin Entlicher 2007-08-22 10:30:37 UTC 
Yes, sure. We can host it under /cvs/debuggerjpda, e.g. /cvs/debuggerjpda/proxy ? Or maybe analyzer is a better name...
Comment 7 _ kherink 2007-08-22 10:49:22 UTC 
i will supply the sources via email later today once i add licenses and clean them up a little
Comment 8 Martin Entlicher 2007-08-22 11:06:11 UTC 
O.K. Thanks.
Comment 9 _ kherink 2007-10-22 05:21:17 UTC 
should i do another performance survey of different debugger operations or are you guys already on top of it for 6.0?
Comment 10 Peter Pis 2008-04-10 22:53:30 UTC 
Changing TM for open issues.
Comment 11 _ kherink 2009-12-01 14:54:28 UTC 
if anyone is interested in tracking down performance issues the tool to analyze the JDWP traffic is available here:

Comment 12 Martin Entlicher 2010-08-20 13:34:14 UTC 
JDWP traffic should be significantly reduced by the fix of http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6457137 and changes applied in issue #186517.
Tested with JDWPAnalyzer.
Resolving as fixed in NB 6.10.

6 years and 1 month later we're there :)
