This document proposes an experiment to increase the permitted TCP initial
window (IW) from between 2 and 4 segments, as specified in RFC 3390, to 10 segments
with a fallback to the existing recommendation when performance issues are detected.
It discusses the motivation behind the increase, the advantages and disadvantages of
the higher initial window, and presents results from several large-scale experiments showing
that the higher initial window improves the overall performance of many web services
without resulting in a congestion collapse. The document closes with a discussion of
usage and deployment for further experimental purposes recommended by the IETF TCP Maintenance
and Minor Extensions (TCPM) working group.
