3 months ago@KseniyaK I used to do this and although obscurity is no substitute for security, I ran it behind a firewall device and then behind net-misc/sslh on port 443 (fwding https to a port with no listener to make it appear the port was open but not connected) - before that when I reviewed the logs I’d see endless password dictionary attack attempts from bots on port 22
@waz @soaska There are other reasons to be cautious about using AVX - older CPUs that support it are forcibly downclocked when the instructions are used so you’d better make sure that your vectorised loops are delivering enough benefits for the 10-20% penalty for all the rest of the code
