[Opensim-dev] resource requirements OpenSim 10+ regions

[Dahlia Trimble]

It's doubtful that Opensim will outperform Linden servers with a similar
load, so I would start with Linden's specs, which I believe are along the
lines of one core and 1 GB ram per full (15,000 prim) simulator. I suspect
Opensim will have a greater hardware requirement than an equivilent Linden
sim until much of the code has been optimized, which may be a while.
