[Opensim-dev] Phantom prims and memory usage?

[John Sheridan]

Ok, I'm trying a little bit of an experiment here and I'm wondering if 
anyone else has tried this and had similar results?  We're running ODE 
on Linux Ubuntu using a vps setup hosted on quad core Xeons.

I'm going on the concept that if an object does not need any sort of 
physical interaction that if its made phantom the server will in effect 
use less resources.  In this case I have one server thats running six 
sims with around 30,000 prims spread between them all.  After going 
around and setting as many objects as possible to phantom (telephone 
poles, windows, tables, chairs, misc props and anything thats not needed 
to keep the avatar from falling out of the buildings) it appears as 
though that server's memory usage has gone down from about 70% (740 
megs) down to 45% (520 megs).  I would estimate that in total 
approximately 15,000 to 20,000 prims were set to phantom.

Thanks, :)
