When I need speed, I drop down to FTP/rcp or some other cleartext protocol.

Moving a terabyte database in an upgrade, I have connected three ports direct (no switch), then used xargs to keep all three connections busy with transferring the 2gb data files. I can get the transfer done in under an hour this way.

I don't currently have a performance need for an encrypted transfer, but one may arise.

I fully understand that. We're using this, along with parsyncfp2 (which you should checkout) to move 1.5PB of data a month across a 40Gb link. Not saying that HPN-SSH is only useful in that context but different people certainly do have different needs.

If encryption was absolutely required, I might try it over s_client/s_server or two stunnels, one in client=yes mode.

I'm assuming that would have different limits than you outlined above, although I don't think they do multi core.
