Subject RE: CPU spikes on trunk
Date Thu, 03 Jan 2013 12:13:02 GMT
Thanks for pointing to visualvm again, will check that first in the future. There is no problem
with trunk but there was a problem with my GC settings. I forgot to add an additional 0 to
-XX:MaxGCPauseMillis so it became too small.

Thanks,
Markus
