Week2 tweaking RMS performance

Hey ppl,

someone must have an idea about this regarding RMS and Dolphin.

First of all, there is the enormous lag in Video-Chats (one on one) ranging
between 1-sec. (at best, which would be fine) and 3.5 min (worse).
Thus raising the question of what are the exact recommendatory specs of the host server.
In my expression a 8x2 state or the art server should be enough (which we have). however the performance is far from acceptable, must be a settings thing.

Oh, and btw. which client specs are adequate to connect to RMS.
