Hmm, I've done it on Solaris, but using GCC. It is very slow:
vtn1% time ssh vifa2 id
uid=139(jnemeth) gid=10(staff) groups=10(staff),0(wheel)
0.0u 0.0s 0:27 0% 0+0k 0+0io 0pf+0w
vifa2 is a Sparc IPX running SunOS 4.1.3 (aka Solaris 1.1.1). Note
that it only took me a couple of seconds to enter my password. Also,
it doesn't have a /dev/random, so it is using prng to generate random
numbers. This adds to the speed penalty. I am currently putting
together another box to replace it.

How about things like USIII, especially the dual core stuff? It
probably won't ever be the fastest, but current stuff should be pretty
decent. It does have other important attributes, though.
