Hi Sean,

My system is windows 64 bit. I looked into the resource manager, Java is the only process that used about 13% CPU recourse; no disk activity related to Java; only about 6GB memory used out of 56GB in total.

My system response very well. I don't think it is a system issue.

thrashing? does the UI respond? is the CPU busy or not?
