Hi Steve, I wonder, did you test with a spinning disk or a solid state disk? Also, I would be interested to know how much the difference is.
Of course it would be nice to have a reproducible test case, but if now, then could you get full thread dumps (once per second for example) and heap histograms (once every 20 seconds is enough)? I usually use the command like way: "jstack -l <pid> >> jstack.txt" and "jmap -histo <pid> >> jmap.txt". I would use an endless loop with "sleep 1" as a shell script.
