I faced this. I wrote a network search engine and used F#. For ease I deployed on Windows. Winpcap is fine, but you don't have a lot of space to easily improve.

Looking at the features the Intel NICs had and how easy it was to use them on Linux... Why would I ever want to try to optimize it on Windows? That said I think the Wireshark guys (linked from the Wireshark site anyways) might have some answers. I know for WiFi capture they had fully functional Windows devices.
