Optimizing Latency in Distributed Systems with TCP_NODELAY

The text discusses the use of the TCP_NODELAY socket option in distributed systems to address latency issues. It explains the history and rationale behind the Nagle's algorithm, its interaction with delayed ACK, and its relevance in modern distributed systems. The author suggests that TCP_NODELAY should be the default setting in modern systems, given the traffic and application mix, and the capabilities of the hardware today.
