[ale] SSH slow to connect?

I have just (re)installed linux on my MVME177 based VME system and I am
(still) having a strange problem.  When I try to ssh to the machine it
takes a LONG time to connect, on the order of 2 minutes or so.  At first
I thought it was because it was trying to reverse map the IP I was
trying to connect from, so I ran iptraf to see if it was contacting a
DNS server at about the time I tried to connect to the machine via SSH. 
It did, so I added the host to /etc/hosts and tried again, this time it
did not connect to a DNS server, but the connect still took about 2
minutes to happen.  Now I suspect the slow connect is related to CPU
speed.  Is this a realistic suspision?  The MVME177 has a 50MHz 68060
CPU in it so its not the fastest thing in the world but at ~100 bogomips
its not that bad.  What else could it be?  Does anyone here run Linux on
an equivalent machine (perhaps a Mac of some sort) that could confirm my
suspisions?  BTW I did not reinstall to try and fix this problem, I
reinstalled because my HDD crashed :(.  In general the machine is not
too slow.  It does not compile the kernel as fast as my Dual 1GHz P-III
does but thats ok ;)

TIA,
Mike

PS: The connect time does not seem to change much when I switch to
another CPU board with a 25MHz 68030 on it.  Atleast IIRC, I have not
recompiled the kernel again so that I could do the board swap, and its
been awhile since I compaired them.  Anyone know how to resurrect a dead
SCSI drive while we are at it? ;)
