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). https://wiki.freebsd.org/SSHPerf --=20 Allan Jude --4OIa529fSVkOWx9Mekp6GN44AIRU7SoaI Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) iQIcBAEBAgAGBQJWRMk7AAoJEBmVNT4SmAt++C4P/iTH+Gd7LmA0RJLkc3WKr9Rs ocR/2fAJBeo9op0yNlqV4H+cLJW6Z1G650+j5gDeV4rE0pglnlOkeGyhUobnDCzw p4okH3RnCK7ufpTEFyAvaB09VLRI8QKDiUpAwyhH7PYStAZP7PVZRssUR6UyeS4A VKJnHrGV9dOHEUKCgjbPAglkKG9rLIvdFqIqp4Wnk9+lnlMmb55YFsvMi1AUV86H w5Q+FrUXm2EjDSW/U6iNw85UMr9/58dXkgdqSe6ZzCwGLvFTbXzDO6NFXL+6Bq1V qH3NACtKi0JxqeK/uwE+HEmCSwyCYOUxFNsBNcNpGQAtjRKUdexW8C67JWlwfGDd p1vrVCrR2a6m7SLErnYc0EiwGxK9MuyPwBtMKoW++6tVxpKEHMUaMyxdVDswzdNM DLl5WChPHhgmHWeg2a6lUA11PcAs3jywOi+XzlSkR+oD+OOgc+vFDwlSu3k5ydsP EE4AxXzIQ8+jIWAnNvZOTfUDCSsen/mTgZRemIyj4ReUIJqwwH2PE3UCVU8/yvi7 dxDtG7b+TPrNIWZnALa3MVeSDZ4odNaLUL1SrALao5Y2b2uk3OfIcZQ7W+gY4Qhc 0i++ZtbQocm37I0V950vfyKbpucI9FOKwTGNcCRJsF07XuD3Gfhn3P3Si1aXaQCA JxyFHNMukdPb+ax10+7p =d8ra -----END PGP SIGNATURE----- --4OIa529fSVkOWx9Mekp6GN44AIRU7SoaI--
