Maybe. That would reinforce my initial statement. But: The time
between pressing [Enter] on the client and getting the login-prompt
from the server (90MHz Pentium1) is nearly zero. Both systems are
running Debian GNU/Linux.

Yes, I can affirm this time.

You do not want to run SSHv1. Use telnet.

Umh, I used to connect hourly to a 90MHz Pentium running GNU/Linux
from a 333MHz PentiumII running GNU/Linux whithout any problems.
Both systems had a 2.4.x Kernel and SSHv2 only (v1 disabled).

Does it really? Would be sad somehow....
And how comes SSH is running so much faster on RS/6000 / AIX?
I will have talkback with a friend who's in the OpenBSD developers
team (They also implement OpenSSH). I hope he knows.

According to a statement of a friend of mine (not the one mentioned
above), only the key-generation process should be faster on intel
processors.
