I have a .NET 3.5 server application that usually has about 8 clients. I’m using System.Net.Sockets for all the networking.

I’ve been told that if a client is running on the same box, it should use localhost:<port> or 127.0.0.1:<port> instead of the machine’s ip or name for better performance. Several people at work have said that this skips some layers of the tcp stack.

But I’m not able to see any performance difference at all in testing (timing how long it takes to get a ping packet from server to client using System.Diagnostics.Stopwatch).

Should there really be better performance in theory?

    No, performance is same in both cases. If you are using your local device ip address, your operating system kernel don’t transport your packets data to your network device and this data don’t be was sended anywhere then you don’t have any ISO layers calculations (encapsulation, decapsulation etc).

    I belive the OS will see this is a local device and you treat it like it was 127.0.0.1. So in fact both will have the same effect.
