I just wanted to bring it to your attention that the university of Pittsburgh provides a HPC-Patch for OpenSSH 4.7 wich may is worth looking at (include it into the base if possible? who knows..). :)
It seams to outperform the normal SSH a lot and this speedup looks kinda impressiv btw. http://www.psc.edu/networking/projects/hpn-ssh/ Here's a direct link to the patch: http://www.psc.edu/networking/projects/hpn-ssh/openssh-4.7p1-hpn13v1.diff.gz Kind regards, Sebastian
