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

Sun Aug 19 12:00:51 UTC 2012

As you might notice. http://www.flickr.com/photos/akirasonoda/7814375104/ A
majority of the OSGrid residents using those "buggy" viewers. And i guess
there is possibly no one in OSgrid who does not have installed one of them
in addition to his favorite experimental viewer...

As you might know Amazon has datacenters located at different places. One
is located in Ireland. I have chosen that one, because the goal of that
party was to have a profiler running in parallel in order to have an idea
to see what is going wrong.

I am really not that comfortable with banning viewers. And I hope to open
this region as sooon as we have evidence the sim can support all those
viwers with a lot of people (15 to 30) simultaneously partying with a
decent amount of lag and no forced logoff because of ACK timeouts, failing
presence service calls etc.
