Yawn. Of course it does! 50,000 concurrent connections way back in early
2000's.

 So, you have, what is it, 50,000 concurrent read and/or 50,000 concurrent
write requests in flight at once?
 By the way, the default “hard” process open-file limit on this system I’m
using is half a million.

It was about how to squeeze in 50,000 concurrent connections on some (now) older hardware. There were many tricks... One of them being zero-byte receives wrt IOCP. Keep in mind that IOCP can mess around with non-paged memory. So, you have to be very careful! You are reminding me of a so-called panic mode when the server would get to a point where shit might hit the fan, do I would dump timedout connections, dump as much cache as I could, but still try to maintain up time during times of really heavy load. It was an interesting time. 23-24 years ago.
