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: <a href="http://www.flickr.com/photos/akirasonoda/7803972118/">http://www.flickr.com/photos/akirasonoda/7803972118/</a> no major problem ... feedback was: Rezzing is better, less clouds ...<div>
<br></div><div><div>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... </div>
<div><div>
<br>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. <div>

GetMesh and GetTexture should be fine in 0.7.4-rc1 (and probably earlier).<br>
<br>
I think the "may lead to poor performance" was rather cautious. If anything, fetching via HTTP should lead to better performance since it's not generating lots of UDP messages that have to traverse OpenSimulator's UDP client stack (and hence appear to be able to hold up/crowd out other UDP messages in the process).<div>

Hi Word,<br>
<br>
Because with those caps<br>
<br>
Cap_GetTexture=""<br>
Cap_GetMesh=""<br>
Cap_<u></u>FetchInventoryDescendents2=""<br>
Cap_FetchInventory2=""<br>
<br>
you won't see any textures on prims ... meaning all prims will be<br>
invisible. Only Singularity 1.7 has this problem and is therefore<br>
banned<br>
The same applies for the experimental Cool VL Viewer which will be on<br>
the banned list as well.<br>
<br>
Once I am certain at least GetTexture and GetMesh won't harm, they<br>
possibly can be also allowed. But right now i do what is written in<br>
the comment of the OpenSim.ini:<br>
<br>
; This is disabled by default. Change if you see fit. Note that<br>
; serving this cap from the simulators may lead to poor performace.<br>
<br>
Poor Performance ... I am sensitive on that .... and it is even worse...<br>
<br>
Take care<br>

Hi Akira,<br>
<br>
Why are you banning Singularity ?<br>
<br>
Best regards<br>

Hi Fleep,<br>
<br>
First, banning viewers is not a good thing, especially not on osgrid,<br>
because osgrid is here for testing the OpenSimulator under real life usage<br>
and as far as i know OpenSim wants to support all of the viewers floating<br>
around.<br>
<br>
Buuuuut ... it is really annoying to have a sim crashing when you have a<br>
party with some 15 to 30 people partying. Therefore I enabled on one of<br>
the 50 sims i am maintaining, the following rules:<br>
<br>
AllowedClients="Phoenix|<u></u>Imprudence|Cool|Singularity|<u></u>Firestorm|0.6.3"<br>
BannedClients="Singularity 1.7"<br>
<br>
Those should support most of the used viewers:<br>

<br>
Firestorm is in, because many people use it. This is the riskiest part<br>
because with my avatar i crash ( or at least produce ACK timeouts for all<br>
viewers ) the sims all the time using the latest Firestorm.<br>
<br>
If you have your own grid, then you can apply viewer restrictions on grid<br>
level.<br>
<br>
Take care,<br>

Hi all,<br>
<br>
I was wondering if anyone was willing to share their list of banned<br>
viewers used in the config files for Opensim? I don't know what the<br>
latest and greatest bad viewers are (or really any of them since I don't<br>
use them!), but if anyone has a good list, I for one would appreciate the<br>
info.<br>
<br>
For the record, I understand that the banned viewer list in the config can<br>
be overridden by a savvy griefer, so it's not air tight security, but I<br>
figure any effort to combat it doesn't hurt..<br>
<br>
Thanks in advance!<br>
<br>
