First thing I'd suggest; Turn off debug mode!!!!! It seems a chunk
of the
Gced objects are coming from preparing strings for log statements
which are
only activated when debug mode is on (for example;
Com.opensymphony.xwork2.util.InstantiatingNullHandler.nullPropertyValu
e(Map,
Object, Object) accounts for 5% of Gced objects, of which nearly
the entire
5% comes from StringBuilter and Log4JLoggerdebug which are only
used when
debug mode is on).
How ??? devMode is already false in struts.xml
I've noticed that's a lot of log4j calls but don't know if they can
be removed!
Thanks
Secondly it does seem as though there's anything wildly wrong here,
there
aren't any single methods which have large Gced object counts
indicating
there isn't a big bottleneck (yes, some show 30+%, but that's
fairly evenly
divided between the methods called by the 30+% method), which leads
me to
one question, how much data are you trying to output? Can you do a
"Save
Source" and tell me the size of the HTML file generated?, can you also
provide the call tree with a call count so we can see how many
times the
methods are being executed?
Thanks,
Al.

Your trace is at too higher level. Can you put a fully expanded copy
of your trace that goes down to the leaf methods.
Done. It's on traceall.html. I expanded only the two most garbage
producing
top call.
Thank you
