Ok! I played with ttcp and think there is another culprit: nfs.

Once again here's the scenario...

      +--------+               +-------+
 st0--o  maat  |<--dump/ssh---<| thoth |
      +--------+               +-------+

... what I noticed was that I also had /usr/pkgsrc mounted on thoth via
nfs from maat.

I just did a "umount /usr/pkgsrc" on thoth and now all is nice and fast

The nfs mount being present affected both dump (with RCMD_CMD=ssh) and
ttcp. There is badness there, no?

However it did *not* seem to affect ftp! Probably because of where the
sockets are??

Please let me know if I can provide more info...
