Strange, we use openssh 2.1.1p2 (just upgraded from p1) on Solaris 2.7 and 8
with no problems. We have to run an entropy gathering daemon (egd), since Sun
don't supply a /dev/random device, which occassionally kicks in a uses some
cpu cycles (as does sshd every so often). But we've seen no performance
problems such that it causes a problem - we use hardware from an E3000 down
to an old Sparc classic (on which I'm quite pleased that ssh actually
performs well!).
Ah!, You have just reminded me that we perform an ssh remote backup from the
classic (Solaris 7) to a Sparcstation 20 (also Solaris 7). The logs show
that backing up almost 1GB took just over 90mins (throughput varies from
around 170 to 200KB/s).
Now that is probably the slowest machine we have, yet even a 2GB backup
should only (?) take 3 hours. So, again, why is my P200 taking over 8 hours??
Weird.
John.
