Dunno, but you might take a look at /usr/ports/security/hpn-ssh/: --- pkg-descr --- High Performance Enabled SSH/SCP from the Pittsburgh Supercomputing Center hpn-ssh is a version of OpenSSH modified to support high-performance bulk transfers (such as with scp or rsync). These modifications are required because: SCP and the underlying SSH protocol is network performance limited by statically defined internal flow control buffers. These buffers often end up acting as a brake on the network throughput of SCP especially on long and wide paths. Modifying the ssh code to allow the flow control buffers to be defined at run time eliminates this bottleneck. WWW: http://www.psc.edu/networking/projects/hpn-ssh/ --=20 (nil)
