Hi Simone,
>4972.437: [GC pause (partial), 1.89505180 secs]
>that I cannot decypher (to Monica - what "partial" means ?), and no mixed GCs, which seems unusual as well.
Oops, I understand that now: 'partial' used to be what 'mixed' is now!
Our portal usually runs on Java 6u33. For the G1 tests I switched to 7u7 because I had learned that G1 is far from mature in 6u33.
But automatic deployments can overwrite the start script and thus switch back to 6u33.
>Are you sure you are actually using 1.7.0_u7 ?
I have checked that in the archived start scripts and the result, unfortunetaley, is: no.
The 'good case' was actually running on 7u7 (that's why it was good), but the 'bad case' was unwittingly run on 6u33 again.
That's the true reason why the results were so much worse and so incomprehensible.
Thank you very much for looking at the log and for asking good questions!
I'll try to repeat the test and post the results on this list.
Regards
Andreas
