Take care that select() is not good for a webserver. From manpage:

       WARNING: select() can monitor only file descriptors numbers that
       are less than FD_SETSIZE (1024)—an unreasonably low limit for
       many modern applications—and this limitation will not change.
       All modern applications should instead use poll(2) or epoll(7),
       which do not suffer this limitation.

Lol.

22 years ago, I worked for Zeus Web Server, which was built entirely around one-process-per-core webserving off select(), and it was so much faster than Apache for serving static content that the developers had built a business out of it. At the time it could saturate a gigabit ethernet link off the largest HP-UX server we could find.

Sure, you should use the modern interfaces, but 1024 connections per process can get you surprisingly far.

Thanks for this. Saw the bug you logged on github too. Agree that poll() should be used instead to avoid the FD_SETSIZE limitation. Maybe in the future when littlekitten webserver grows to be a big cat...
