that's totally correct, but we just wanted to see anything on how OFBiz
performs. At least we know now, that something is strange with that
machine, because creating instances of e.g. HashMaps is slower and it
seems to be that each method call on this machine takes more time than on
other environments. Perhaps we should upgrade the JVM. We'll see.

Yes, that is our current plan. Yesterday I've read a bit about The
Grinder, which was proposed on this list a few days ago, and today I want
to try it.

Exactly that's the point why I've posted the issue to this list. I hope
I'll find the problem. If I can say I've found it, I'll post my results.

Thanks for your answer.

Best regards,
Fabian.
