IPC in Rust – A Ping Pong Comparison
wanted to explore different ways of communicating between different processes executing on the same machine, and doing so as fast as possible. We're focussing on high speed inter-process communication (IPC), but some of these approaches can be extended across a network.

System calls on Linux are complex, and there are various mitigations, but having to wipe registers, validate, drop down into the kernel ring, get the output, and then undo those steps takes time.
