When you're moving terabyte files, 100Mbps is way too slow.  :-)  We looked 
into this issue because at gigE speeds it became obvious that fast CPUs 
were sitting almost idle during scp, thus the encryption latency was 
probably not the main problem.  I suspect that the tests were done on gigE, 
though we now have 10gigE links to a few other sites.

Even though a patched ssh is pretty speedy, I don't plan on getting rid of 
krsh  or kftp anytime soon.  But still, we've found that "everyone" has scp 
or sftp while few of our users have kerberized tools, so ssh is slowly 
taking over.
