Reduced Latency for
Sometimes your interactive TCP-based applications lag.
This article shows you how to reduce the worst latency.
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.
