Michael, Rule of thumb is 80% for equivelancy. In other words, a 1.8 gig 64bit is equal to a 1gig 32 bit. Heap. Or you can just multiply times 2 (which is usually what I do). So a 6 gig heap is roughly 3 or more times the size of your 32bit 1 gig heap. If your server is dedicated to CF I think your 6 gig heap is great. Takes most of the physical memory for CF and leaves 2gs for the OS, monitoring etc.

I understand I can use more than the standard 1 gig but has there been any work on the best settings? Otherwise I'm thinking to start with 6 gig maxheap and 4 gig maxperm. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:356691 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
