I get the feeling you've had a bad experience with the API and that colours your opinion of the overall design of IOCP. It's really quite well thought out. Also in my experience it handles slightly more concurrent connections with a fair bit less CPU usage. There are some weird and not very nice parts + limitations to the API that makes it pretty hard to write cross-platform things with it, granted.
