Hi,


I've been tuning a Java 7u51, Solaris 10, T4 system with 24G heap.
My customer is not very happy with the remark pauses of  up to 2  seconds.
  -XX:ParallelGCThreads=48 turned out to be the optimum. Here is the log 
file
which contains the java args at the top:

Any idea to drive the remark stop times further down?


Thanks and Regards

Thomas
