Problem 2. World never loads fully. Only about 50-60% of all meshes is
visible in 0.42 viewer, with Naali, the situation is even worse.
Sometimes you also have few prims missing and rectangular holes in the
ground. This is due to the way LLUDPClientStack is implemented in
0.6.9. There is also a bug there (see problem 3). Older
This is fixed in current Naali and Modrex releases (the modrex in Taiga
0.1.1), with the usage of http for asset downloads. In our tests so far
it works really well now, all meshes and textures come reliably and
quickly.
For more information, see Jonne Nauha's recent post to the -dev list.
The first solution, which requires running a command on the server side
to associate a URL for each asset, works against Naali 0.2.1. The other
solution to use an Opensim CAP to get the baseurl for assets on that
particular asset server is implemented in current Naali develop and is
going to be included in the 0.2.2 coming after next week (we do time
based releases every 3 weeks now, after each dev sprint).
a. distrubute world viewer to users with all meshes already placed in
cache (improves situation a lot, but not solves the problem completly.
Increases client size, make difficlut to update your world)
This has been done here too, Naali even supports that as a feature so
that you can add a content pack to your client install. Was done before
the work on getting the http asset pipe was finished, earlier this year.
c. I have read that new Taiga server supports http assets downloading.
This might improve situation (only when using new Naali viewer). When
I tried to test, this, I was unable to run Taiga with my database
(example installation with empty database works well, but useless).
With our data set, it throws multiple exceptions on startup, have
problem with logging users in, and a number of other issues.
Bleh, should have read the post fully before started replying, of course
you knew about this already :) Well, at least there was some specific
info about in which versions it works and how.
We haven't worked too much on migrations yet, one reason is that we are
also using the dotscene import to bring the scenes in from how they have
been exported from e.g. Blender.
AFAIK e.g. the fishworld demo is now running current Taiga though, so
migrations should work? Also some other demo worlds have been migrated
to new server versions every once in a while. Could you perhaps provide
your problematic dataset so that people who know about the migrations
could debug that?
The maximum number of avatars that can login to the region is 16.
Anything more makes world absolutely unusable. Every five minutes
somebody is thrown out, and every 15 minutes the server crashes and
must be restarted. The maximum number of avatars that can work
comfortably is 8.
Solution: I don't know any solution here yet, we are working on it.
Any help from anybody would be greatly appriciated
In osgrid tests they have reached something close to a hundred (>80?)
but indeed then things become slow. I have heard from osgrid testers
that something like 40 would be usable with 0.6.9, and the Wright Plaza
weekly meetings host I think typically >20 AVs and run ok?
Did you look at the Intel work on this? They target 50,000 or something
users in the same place :) , and seems that with their client manager
idea that is possible, but not a short term solution (hopefully they
have some sort of solid prototype by the end of the year - first test
was iirc in last August running 400 text-only test clients from the same
computer).

Thanks for the info about the results in your testing, hopefully the
prob with your data and other possible probs with current modrex
versions for you are solved soon so you also get to test the http assets
etc.

We are implementing realxtend based learning game during this fall. I like to
enquire if somebody have made some performance tests and could share the
results with us.
Folks at Intel did some profiling and optimizations last year to
Opensimulator and are now continuing to work towards allowing large
scale mass events etc., they gave a nice presentation in a workshop
recently and the material is on-line:
paper athttp://vw.ddns.uark.edu/X10/content/ARCHITECTURE--Designing-Extensibl...
and the presentation with more about the future plans
inhttp://vw.ddns.uark.edu/X10/content/Extensible%20Virtual%20World%20Ar...
Otherwise the opensim-dev mailing list and sciencesim, osgrid etc admins
are knowledgeable about this. Realxtend is not used as much for heavily
used things yet, and the server side performance is probably quite
identical 'cause modrex doesn't introduce much additional computing.
BTW we are working on a learning environment for school kids using it
too, pilot testing etc. will probably be done during fall in that
project as well. There's a bit old/earlier news announcement about it
athttp://maxping.org/business/real-life/realxtend-virtual-worlds-powere...
(maxping seems to be offline now though?), more info coming late this
month / early july probably and we can of course talk about it too if
you're interested.
