<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I thoroughly agree. I have been running 16 OS
processes (256 regions) on the same box for a few years now and have never seen
these problems. Last semester we taught a class AND ran two tests:
first we set up the GMU Fairfax campus on first a 4 OS process install
(4OSx16regions) and then completed the class on a 1 OS process install with 64
regions. Both worked quite well although the 1X64 with +18K prims was a
"little" laggy but still tolerable.</FONT></DIV>

<DIV><FONT size=2 face=Arial>My personal preference from a "headaches"
perspective remains a distributed approach. The use of dual Intel
multi-core/hyperthreaded CPUs and a strong, well-threaded operating system
is hard to beat. Best of all, if I understand correctly, "may be" the
cloud architecture that our friends out on the west coast are using .....
I'd really like to know more about how to set one of "those" up.</FONT></DIV>

<DIV><BR></DIV>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?

I rebooted my system and checked stats. The memory used started
at 1205 and over night without any use that I know of, it rose up to 5349
MB. I would be saving cost of installation, with my knowledge and my
wife's good sight, I can do the install myself. 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=gmail_quote>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><BR>On 22/05/12 15:57, InuYasha Meiji
