Improving v2 connection exchange.

[mouring at etoh.eviladmin.org]

I just finished net-installing OpenBSD on my Sparc (yay.. <sigh>), and I'm
noticing how extremely slow it is to connect (20 - 30 seconds) as compared
to v1 protocol to the Sparc.. or even v2 from my dual 533mhz to itself.

(The sparc is a ss20 w/ a 150mhz processor, it's works nicely after the
key exchange is finished.)

Is there any reasonable way to improve the connection speed for v2 on
slower hardware?
