Can you not run out of sockets though? I know it used to be a thing anyway. Maybe it's handled somehow nowadays.

- toast0 6y agoYou can run out of sockets, but that's easy to tune. I don't know the limits on other systems, but FeeeBSD lets you set the maximum up to Physical Pages / 4 with just boot time setings. So about 1 million sockets per 16 GB of ram. Worst case, if you start running out of sockets because you're sleeping, sample the socket count once a second and adjust sleep time to avoid hitting the cap. Also, you could use that sampling to drive decisions about keeping http sockets open or closed. I should add, select on millions of sockets is going to suck; so you'll need kqueue/epoll/whatever your kernel select but better interface is.
