No problem!

Hmm.  I am evidently doing something wrong.  I get an order of
magnitude better write performance from an scp compared to a write
over an nfs mount.  I am just looking at "blocks out" from a "vmstat
1" running on the server.  I see, roughly, 300-400 with NFS and and
about 4000 from an scp.  I am not sure if those are 1k blocks or 4k or
something else, but the order of magnitude stands out pretty clearly.
