It has a very easy explanation - the volserver is not multithreaded, as
fileserver (in AFS 3.5/3.6), so if you have multi-CPU machine you can expect
better performance using fileserver...

Yes. Same numbers here. It is more efficient to use vos dump in terms
of total used resources, but because all enhancements went into
serving files, using the client is a lot faster. There is a bottleneck
somewhere in the volume server.
