The time to do an ssh handshake is ~ the time that mwhudson reported. 
robertc at lifeless-64:/usr/share/doc$ httping -g http://squid-cache.org
PING squid-cache.org:80 (http://squid-cache.org):
connected to squid-cache.org:80, seq=0 time=535.30 ms 
^C--- http://squid-cache.org ping statistics ---
1 connects, 1 ok, 0.00% failed
round-trip min/avg/max = 535.3/535.3/535.3 ms
robertc at lifeless-64:/usr/share/doc$ time ssh squid-cache.org true

real    0m5.099s
user    0m0.010s
sys     0m0.040s

So ssh handshake time here is ~4.5 seconds.

And yes, I can tell 4.5 seconds.
