Job Snijders discusses the Nagle’s algorithm and its implications on TCP congestion control in a recent RFC. He mentions how the algorithm can lead to increased latency by coalescing small packets into a single TCP packet. Despite its historical relevance, the usefulness of Nagle’s algorithm in modern times is debated. Snijders introduces a sysctl to disable Nagle’s algorithm on the entire system, highlighting applications that have already taken this approach. The potential change in default settings is also mentioned. This proposal aims to improve interactivity and throughput in TCP connections.
