what exactly do you mean by "removed the code that was using netaddr library"? change the api so that packet base classes take on-wire bytes as dpkt does? or replace addrconv's use of netaddr with some code using struct.pack/unpack?

For the benchmark test, I used a normal ip/udp and ip/tcp packet. ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
