I’m looking for some data to help me decide which would be the better/faster for communication between two independent processes on Linux:
Which is worse: the system overhead for the pipes or the tcp stack overhead?
Updated exact requirements:
In the past I’ve used local domain sockets for that sort of thing. My library determined whether the other process was local to the system or remote and used TCP/IP for remote communication and local domain sockets for local communication. The nice thing about this technique is that local/remote connections are transparent to the rest of the application.
Local domain sockets use the same mechanism as pipes for communication and don’t have the TCP/IP stack overhead.
