Mesh avatars are a hot thing on SL and on OpenSim worlds alike. The backside of it is that mesh avatars are a heavy load for any server as they have to process all the vertexes of the mesh shape. This is where the OpenSim community stepped in and created new, high quality but low vertex mesh avatars that load many times faster than the currently known high quality mesh bodies.
