There is a way to do a little sort, gain a cohort and execute it. For 
instance all reads, writes, connections, accepts are all organized in a 
cohort.

Instead of processing a read, write, read, read, write. Say:

read, read, read, write, write

To get better locality. I remember some functions on winnt. AcceptEx, 
ConnectEx, TransmitFile, TransmitPackets, ect... ;^)

The main thing to use to wait on io completions:

https://learn.microsoft.com/en-us/windows/win32/api/mswsock/nf-mswsock-acceptex

https://learn.microsoft.com/en-us/windows/win32/api/mswsock/nc-mswsock-lpfn_connectex

https://learn.microsoft.com/en-us/windows/win32/api/mswsock/nf-mswsock-transmitfile

https://learn.microsoft.com/en-us/windows/win32/api/mswsock/nc-mswsock-lpfn_transmitpackets

I used to use them all the time back in the day.
