In place of RPC, 1 they may substitute a different term or technology like REST, microservices, gRPC, WCF, Java RMI, etc. Why RPC is “faster” It’s tempting to simply write a micro-benchmark test where we issue 1000 requests to a server over HTTP and then repeat the same test with asynchronous messages. And this makes sense!
