I did a few quick (and dirty) benchmarks and it shows that the NONE
cipher definitely makes a difference. Version of OpenSSL also seems to
make a difference, as one might expect.

Note: openssh from ports seems to link against both base and ports
libcrypto, I am still trying to make sure this isn't corrupting my
benchmark results.

I am still debugging my dummynet setup to be able to prove that HPN
makes a difference (but it does).
