Also Michael - 2gb perm size seams rather large generally speaking (unless you have tons of cfm/cfc files). Further if your server has 8GB of ram, and you are setting 6GB max heap and 2GB max perm size then you are not leaving any room for the OS to operate when things get full. I thought

your 6 gig heap is great. Takes most of the physical memory for CF and leaves 2gs for the OS, monitoring etc. -Mark -Original Message- From: Michael Dinowitz [mailto:mdino...@houseoffusion.com] Sent: Monday, September 02, 2013 12:18 PM To: cf-talk Subject: Good jvm ram settings for 64 bit
