[Opensim-users] List of banned viewers for config files?

Sat Aug 18 15:07:52 UTC 2012

Should be fine... is the correct wording :-) It works fine for Sims with 1
to 5 Avatars simultaneously which is possibly 99.9% of the whole Landmass
served by OpenSim, but on crowded spaces very distant (Europe) from the
Asset- Inventory etc. Severs ( California ) it does not... especially if
the Cache Hit Ratio is low. Since November 2011 when those caps were
introduced we only had problems which could be mitigated by disabling those
caps and with the viewer bans in place we had quite a successful OSG5B
Friday Party with 37 Avatars simultaneously partying without restart ( okie
by the end of the party at around 01:00 CET the presence service went
somehow corrupt and it was no longer possible to join the party ). Failed
to verify presence or something like that was the message in the log.
Yestertday again 22 People with the viewer restrictions i have in place
plus disabled lindencps:
http://www.flickr.com/photos/akirasonoda/7803972118/  no major problem ...
feedback was: Rezzing is better, less clouds ...

But for sure we'd like to welcome all Viewers at the party... enabling
getMesh ... should not be that much of an issue, because not too many
Avatar wear Meshes... on the other hand, most of the visitors still use the
imprudence especially if we enforce it somehow by banning most other viewer
capable of rendering meshes, therefore there is no big rush to enable
getMesh again...

Right now I am thinking of factoring the whole HTTP stuff out of the
OpenSim into a separate Process, in order to have OpenSim doing what it can
best, acting as a Region Server calculating physics and executing scripts
and serving legacy UDP Packets to the Viewers. I hope to be able to start a
Proof of Concept rather soon. In parallel I will do further testing with
the different viwers and the different combination in order to get further
insights.

take care
Akira
