Up: The effect of multiplexing
Multiplexing HTTP over, standard window size, TCP connections between
international caches, connected by an asymetric satellite/terestrial
link, offers significant performance advantages.
The number of TCP connections between the proxies is important. To
avoid the link being under utilised around 50 connections were
required for an E3 satellite/fiber combination from NZ to the US.
However additional connections are needed if the best page latency is
required. In this case around 70 connections were required.
Nothing in these results suggests the asymmetric delay case behaves
differently to the asymmetric case.
