It is odd to see this topic here without any context. I spent a decent time in the early 2000s debugging performance issues caused by the poor interaction between Nagle's algorithm and delayed ACKs (it's prominently called out on the wikipedia page). Now the effects are widely known and most latency sensitive applications will just disable nagling. I believe John Nagle posts here occasionally.
