We ran into memory issues when we had 32 regions on a single simulator and shortly thereafter switched to ~ 4 regions per opensim process architecture. The overall memory allocation went up, but the performance improved considerably. Have you tried portioning things out across multiple opensim processes?<div>

Getting all the parts for the upgrade to a AM3+ 8 core bulldozer on a FX990 MSI mobo and 32 gig of crucial DDR3, for under $600 would be worth it for opensim or not?<br>
<br>
It will take me sacrifice and lots of effort. I didn't want to go through all that and find out even that won't run my 56 regions well. I thought I might have set something wrong. I double checked last night to be sure I used MySQL for cashing regions and not the default memory setting. I did it right, so it wasn't that. Anyone know of any memory leaks in the ODE or something else to do with version 7.3.1?<span class="HOEnZb"><font color="#888888"><br>

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.<br>
<br>
Unfortunately, memory usage on OpenSimulator will go up and down quite a bit as many objects are allocated before the GC kicks in.<br>
<br>
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.<br>
<br>
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.<br>

Now I have a lot more I want to add to my grid. I currently run all that you see in my tag lines.<br>

Opensim User: Standalone Grid on Version 0.7.3.1 with 56 Regions<br>
on Windows 7, 64-bit. Phenom 9500 2.2 ghz Quad Core, Terabyte Hard<br>

I only have one sim with much on it, I was planning on making the other sims well forested and a couple more villages<br>
and then Shuri Castle from Okinawa in the middle. The reason for 56 regions was to make a nice 1.5 mile landscape all<br>
the way around the castle and surrounding villages.<br>
<br>
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<br>
32 gig DDR3, am3+ bulldozer motherboard. Looking at what little it took to fill over 6 gig of ram, I am worried after I<br>
save up a while and get the upgrade that it won't be enough to do all the things I dream of.<br>
<br>
Am I over reaching? I thought opensim even in 64bit used some disk cashing, and wouldn't use all the available ram? I<br>
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<br>
shutdown a program warning from windows 7.<br>
<br>
Info is welcome.<br>
