I remember a little test that Microsoft made wrt 50,000 concurrent OVERLAPPED ops in IOCP vs an event driven model actually creating a windows event per connection multiplexing WFMO in several threads. The event model did not perform as well, but it did not do too bad either. I wonder if I can still find that paper. Back in 2002 or something. Hard to remember right now.

 I just found an old post from me back in 2003 with a link to the paper:
___________________
You can get 50,000+ concurrent connections using IOCP, check out the
following link:
 http://www.microsoft.com/mspress/books/sampchap/5726a.asp?#128
 You do have to do some memory management to get there, like posting zero
byte receives to ensure that pending recvs don't lock their buffers, you can
also restrict the amount of pending sends the server has all together
