that does clearly help, though I don't think it's anywhere near as
stunning as the difference between OpenSSH and SSH-3.x.....

I don't really know for sure (esp. w.r.t. OpenSSL and OpenSSH), other
than what "egrep 'float|double' */*" shows in src/dist/openssl/crypto).
(which seems to be most of them :-)

All I know for certain is that SSH-2.x and SSH-3.x have always
exclusively used one or another of the various "bignum" or similar
integer-based math libraries.  The only use of floating point I can find
in SSH-3.x has to do with some tiny part of ASN1, as well as with timing
and statistics keeping.

;-)

No, openssh is, of course, pgksrc/security/openssh  :-)

You should try pkgsrc/security/ssh2 on your slow machines.
