[Opensim-users] Rationale for limiting number of listeners

[Dr Ramesh Ramloll]

Hello,
I was wondering if anyone can explain or throw in a few ideas on the
motivation for limiting the number of listeners on a sim.
http://opensimulator.org/wiki/Configuring_Scripting


   - max_listens_per_region - Change the max number of llListens per
   region. Default is 1000.
   - max_listens_per_script - Change the max number of llListens per
   script. Default is 64.


I have one application which I modified to take into account the
max_listens per script which is 64.
After changing it, the application grew happily again until it is now
hitting the max_listens_per_region.
I have some thought on how I may further reduce the number of listeners I
use, but am wondering whether it might be a waste of time.
For e.g. I could further reduce the number of listeners by making sure
every object/3d entity I use does not have more than one listener. However,
I will then need to queue up messages that go between the various objects
and squeeze everything through only one listener channel ... rather than
have data flow between parallel listener channels. Right now, every object
use two parallel listener channels. I do not yet know the impact on
performance between the two approaches. What do you think?
Now question comes up, say, I double max_listens_per_region, what do I
stand to lose by doing so?
Sorry for the questions .... which might be nooby, but I cannot examine
underlying opensim infrastructure to find out. Am far more focused on
application layers.
