Performance of sockets vs pipes

Question

I have a Java-program which communicates with a C++ program using a socket on localhost. Can I expect to gain any performance (either latency, bandwidth, or both) by moving

Answer 1

For local processes communication pipes are definitely faster than sockets. There is a benchmark.

I think even though socket is flexible but it can also lead to bad code design. While using pipe it enforces you to design the architecture of your project like which process should be the parent which should be the children and how they cooperate(this will determine how pipes are established) and assign different functionality to processes. Your project design this way will have hierarchical structure and easy to maintain.
