Regardless of alternatives to NFS, it seems to me that the first
thing to do is isolate the interface performance from the NFS
performance. If you can use ttcp or something similar to measure
the TCP/UDP performance over the same link, that should help
determine whether it is an NFS-specific problem or a more general
That's what I should've said if I wanted to be helpful. On Linux I
suggest iperf (multiple threads) or multiple concurrent copies of
netperf. It takes more than one thread to saturate the link. Then after
you made sure that works, then you can go on to seeing how slow NFS
On NetBSD I'm not sure.
