Using the hacky inferno-npe async clunk implementation, from october 2010; from a Linux server running inferno-npe to a Linux client running inferno-npe; latency ~15ms. Getting the sources of cwfs from the server fell from 5.6 sec to 4.5 sec. For the 9 kernel sources, 51 sec fell to 41 sec.
Got better results with sources (40ms away) but don't have the numbers handy. -- vs
