[-- Attachment #1 --] Hi freebsd-current@, I know that In-Kernel TLS was merged into the FreeBSD HEAD tree a while back. With 13.0-RELEASE around the corner, I'm thinking about upgrading my home server, well if I can accelerate any SSL application. I'm asking because I have a home server on a symmetrical Gigabit connection (Google Fiber/Webpass), and that server runs a Tor relay. If you're interested in how Tor works, the EFF has a writeup: https://www.eff.org/pages/what-tor-relay But the main point for you all is: more-or-less Tor relays deal with 1000s TLS connections going into and out of the server. Would In-Kernel TLS help with an application like Tor (or even load balancers/TLS termination), or is it more for things like web servers sending static files via sendfile() (e.g. CDN used by Netflix). My server could also work with Intel's QuickAssist (since it has an Intel Xeon "Scalable" CPU). Would QuickAssist SSL be more helpful here? I'm asking since I don't know whether to upgrade my home server to 13.x or leave it at 12.x. Yes, I do know we need a special OpenSSL to use kTLS. -Neel [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEEFpeUj+sDItoNIly9vzSRBRPfYX0FAmAIkLsACgkQvzSRBRPf YX32lQgAmubLcb2ZwNDhct9DyQyPlfEzKNdWZeM0tmO8js/CgxGz8OmRSWxUYTP3 INsihSVd1TBHGsYqHwFR0jMYB4yy26rlGZO+F7jz8WsZN+R//MH3jE68CwNKMYPk ww622KczuxLdSLrhek/Dyq927teOYJE9BKJMed6Rlhx0eMN9Ic7OZrbhgrPwdM9M LbWusAP/4aLDtyTRE9ANjzsyoGH30K/SQoSTEihODLx3zd0sNo1NJVu70Vn53TWj 0/6XQr296mh7q5zA56bqkcuFqInlghF1OTIm7f82UR+tSZ2xpJWW7Yb/YwKvzcTH X7zuKROAevTrMfXTnjO5lmFtB8B8Bg== =/yZF -----END PGP SIGNATURE-----help
