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.

Subject: Good jvm ram settings for 64 bit ColdFusion


Does anyone have any suggestions for good workable ram settings on a 64 bit
CF10 install on a box with 8 gig of ram? 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.
