| The asset / inventory servers aren't anything special -- script code is run locally, as are physics, the actual grid doesn't matter there.
Knowing the code on the underlying systems however, I'm not entirely sure how Sakai can be making the claim that it will scale - I know for certain that it wont. It's very primitive and needs a lot of work done to it in the long run, you can throw extreme amounts of expensive hardware at the problem, which is LL's solution -- but in the long run the more elegant appropriate solution is to decentralize things (which OSGrid doesnt do, as OpenSim doesnt support proper decentralised assets yet).
That being said, I know OSGrid.org is about to shift to some very powerful hardware, the current thing it's being hosted on is somewhat substandard. |
