Thanks Saptarshi. These settings worked like a charm. I guess I still need to add some more memory if I want to update our big dataset frequently.

With your settings, I think there will be too much paging happening and the heap space is the worst place to page. The reason for the paging is you might have nearly free 2.5GB RAM available (windows might use the remaining) and you've set the heap space from 3Gb to 6Gb, which will always nearly page. So, I would say the -Xms1024m -Xmx1500m should be safest for 4Gb, given that you'd run parallel GC in some memory that will be beyond the heap. All of this assuming that you have x64 Java as well... just having windows x64 won't be enough. --- Regards, Saptarshi PURKAYASTHA My Tech Blog: http://sunnytalkstech.blogspot.com You Live by CHOICE, Not by CHANCE On 22 February 2013 22:53, Wilson,Randy <rwil...@msh.org<mailto:rwil...@msh.org>> wrote: Does anyone have suggestions for the optimal settings for JAVA_OPTS on a 4 gig Windows 7 64 bit OS?
