>> You might need a VM with this fix. 6782663: Data produced by
PrintGCApplicationConcurrentTime and PrintGCApplicationStoppedTime is not
accurate
OK so that's the early access for 6u21 by the looks of it. I'll repeat a
run on that JVM (and with the safepoint stats).
>> If the log doesn't show a [GC...] line at a safepoint, then there is
not GC activity during it
does this mean that the actual time stopped due to GC is the one
immediately after the GC line?
>> You could use -XX:+PrintSafepointStatistics etc. to figure these out.
which other flags should I look at?
Cheers
