It's not VAX-related, this is the fact on every platforms i think, even on
fast <censored> machines. It is just the initial handshake stuff, the
connection works fast then. (Even hardcore tunneling like NFS via tun-device
and the vtun program :)

Maybe host-lookup-stuff? It is not even NetBSD-related, it seems to be OpenSSH-
related. Would be interesting what it is, as SSH2 on other machines in my
company (i think this is not OpenSSH) works very fast, but OpenSSH on quite
fast RS/6000 (some 6-CPU stuff, very fast!) machines also is that slow with
protocol version 2.

Any hints? ssh -v didn't tell that much... The only thing to see is:

** <here happens the biggest delay> **
debug: bits set: 1027/2049
debug: Sending SSH2_MSG_KEX_DH_GEX_INIT.

And top tells me about 50% load for each ssh and sshd (ssh was to localhost).
