I'm very surprised at the big difference between actual heap allocation (883 mb) and actual process allocation (6193mb).
You might want to monitor memory usage over time - it might be that some kind of peak in heap has put the process
memory up to a permanently higher level.
Unfortunately, memory usage on OpenSimulator will go up and down quite a bit as many objects are allocated before the GC
kicks in.
That said, 64 regions on a single simulator is definitely a stretch, I think. You might want to check what the
difference is between your empty sims and the one with data.
I believe there is scope for better memory efficiency in OpenSimulator but it might be difficult to make really huge
savings. Unlike a web-server, OpenSimulator (and many other VE systems) has to keep data permanently in memory for
speed of response.

Now I have a lot more I want to add to my grid. I currently run all that you
see in my tag lines.
Opensim User: Standalone Grid on Version 0.7.3.1 with 56 Regions
on Windows 7, 64-bit. Phenom 9500 2.2 ghz Quad Core, Terabyte Hard
Drive, 8gig DDR2 RAM. Used XAMPP to load PHP Version 5.3.0, Apache
and MySQL 5.1.41-community edition. Groups, Profiles, Voice and
Offline Mesages all working. (Not yet Public, 6 users allowed Now).
I only have one sim with much on it, I was planning on making the other sims
well forested and a couple more villages
and then Shuri Castle from Okinawa in the middle. The reason for 56 regions was
to make a nice 1.5 mile landscape all
the way around the castle and surrounding villages.
Am I expecting to much of my system and Opensim to be able to do this on one
computer. I plan to eventually upgrade to a
32 gig DDR3, am3+ bulldozer motherboard. Looking at what little it took to fill
over 6 gig of ram, I am worried after I
save up a while and get the upgrade that it won't be enough to do all the
things I dream of.
Am I over reaching? I thought opensim even in 64bit used some disk cashing, and
wouldn't use all the available ram? I
still want to be able to do other things with my machine while running my grid.
Seems I can't always do that without a
shutdown a program warning from windows 7.
Info is welcome.
