PCap性能

Question

Which c-sharp wrapper of Pcap is fastest? How fast is PCap compared to using sockets?

Answer 1

I believe Pcap.Net is faster than other wrappers since it uses C++/CLI wrapping instead of PInvoke.

In general I've never encountered performance issues with WinPcap (it also depends how you use it).

Answer 2

SharpPcap is appropriate both for capture (sniffing) and transmission (similar to UdpClient and TcpClient). I've used it in an application for high-performance UDP transmission and it could be tweaked to be significantly faster than UdpClient (there are examples of high-perf sending in the source).
