Latency impact while listening at eth0, lo and any on Linux

[Sergey Gomanyuk <Sergey.Gomanyuk () amdocs com>]

Hello,

I use pcap library to develop a tool that measures on the fly network latency (a time between receiving a request and 
sending a response) for HTTP, DIAMETER and other protocols. My tool is compiled for x86_64 Linux , So I noticed 
significant latency growing if my tool listening traffic at 'any' interface in compare with listening at 'eth0'. 
Listening at 'lo' also increases latency.

So I wander why does latency increase and can I do something to reduce latency impact while capturing traffic at 'any' 
or 'lo' interfaces?

Regards,
Sergey Gomanyuk
