Are you tired of having to wait for seconds for your networked real-time application to respond? Did you know that Linux has recently added mechanisms that will help reduce the latency? If you use Linux for VNC, SSH, VoIP or on-line games, you should read this article. Two little-known TCP modifications can reduce latency by several seconds in cases where retransmissions are needed to recover lost data. In this article, I introduce these new techniques that can be enabled per stream or machine-wide without any modifications to the application. I show how these modifications have improved maximum latencies by several seconds in Age of Conan, an MMORPG game by Funcom.
