Hi,

If other transfer protocols can truly achieve close to 100Mbps, and it is
only with NFS that this difference can be observed, one is led to examine
NFS.

What are the exports files on server1 and server2? What are the name
resolution mechanisms the servers deploy - are they identical? Are the
mount commands being used on the client identical (with respect to
options)? Are portmapper,nfsd,mountd,statd & lockd running in identical
ways on both machines?

Can you perform a trace on the client of a small file copy to each server
and compare the differences?

Good luck,

Stephen Worotynec
