I am building cross-platform application, consisting of several modules, exchanging with each other.
That means my question is related to both Windows and Linux.
Q: If using TCP/IP for inter-process communication, is there any kind of special optimization, performed by OS in case both endpoints are on localhost?
Somewhere I've heard, in this case Windows can bypass network drivers and use just shared memory. I have no idea about the source/proof of this statement, but the idea to switch off some unused stuff sounds logic.
Is that true and if yes, where I can read the details?
