Low-level UDP network programming performance comparison on Linux

Abstract

This article presents some low-level UDP based net- work programming methods and compares them by measuring the number of transmitted messages per second on x64 and POWER9 servers. The examined methods are: a naive imple- mentation with busy waiting variants; single- and multi-threaded synchronous and single-threaded asynchronous implementations using Boost.Asio; and an implementation using the sendmmsg() and recvmmsg() system calls for sending multiple messages at once.
