For my Masters&#x27; work, I needed high speed tx&#x2F;rx on Windows and looked into the same things you did. I can&#x27;t find the statistics for the tests I ran, but WinPcap&#x27;s speeds weren&#x27;t much better than Winsock&#x27;s, which was fairly poor. The solution I used was an NDIS kernel filter and protocol driver which pushed the packets into user-space memory. Luigi Rizzo has recently added a Windows port of netmap to his repository, so you might want to look into that: <a href="https:&#x2F;&#x2F;github.com&#x2F;luigirizzo&#x2F;netmap" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;luigirizzo&#x2F;netmap</a>
