I have similar experiences here. With FreeBSD-6.1 as client (using an Intel
etherexpress card at 100 Mb/s) and FC5 server i see full wire speed for file
transfers via NFS.

I have the same impression. The 6.1-RELEASE client seems to work well.
Yesterday i have upgraded my 6.0 (*) box to 6.1 and i have not seen a single
NFS problem after that. Moreover i am using rpc.statd, and rpc.lockd
and they work OK and are really functional.
I have the following sysctl which may have an effect on the problem:
vfs.nfs.access_cache_timeout=5
So it may well be that it is the FreeBSD NFS server code which has problems.
(*) 6.0-RELEASE client definitively does not work OK for me.
