> Currently our connection throttling setting limits the total number of FD's that ATS can use. In addition it has pro-active code that stops taking connections as that limit is approached. So we can theoretically use more FD's than we request and still have that setting be effective. Additionally epoll can use a lot of FD's if we use it for things like AIO and timers. Modern Linux systems have many millions of FD's available. I think we should use more FD's by default but have a setting that we can lower it back down. I propose the default be 90%.
