Yikes! On the 840AV, 040/40MHz, I did notice that openssh is noticably
slower than ssh. The mouse doesn't respond for a few seconds, but only
a few. That's with both using the blowfish cipher. With openssh's
default of triple-des, vs. ssh's des, it could well be much worse.

I bet the real difference turns out to be in ssh's Big Number library
(in m68k assembly) vs. openssl's m68k assembly. It might be worth
looking into. In the meantime, try blowfish instead of 3des.
