It is not distributed `round-robin', but `first non-busy server gets
it'.  Hence, there's this decreasing amount of time the various
servers spent.  Since your last server has only spent one hundredth of
a second yet (which is presumably its startup CPU consumption), i
don't think the load on your nfsd's is your bottleneck.
