[Opensim-dev] Auditorium for 500

I did some testing a couple months ago and found that sitting avatars
present much less load than avatars that are standing, walking, or flying.
Also there are other things going on that can compete for CPU resources,
such as scripts and updates for excessive prims. If you have few scripts
running and fewer prims/unique textures to download for each client who
attaches to the region, and if avatars are seated and requiring less
processing from the physics engine, then it stands to reason there will be
more CPU resources available to process chat and viewer updates from the
stage performance. This behavior is consistent with tests I've run.
On the subject of neighboring regions, OpenSim does little processing to
test whether agents on neighboring sims should be receiving update events
and this may cause excessive update traffic if there are several neighboring
regions hosting avatars, even if they aren't watching the events of
interest. Keeping your high traffic regions isolated to as small as possible
of a cluster size may help reduce the effects of this potential performance
drain.
