At the IETF BOF on Wednesday, I mentioned this paper, and was asked to post the URL on the mailing list. Sorry, this is in HTML with GIF inlined images for the graphs; a Postscript version exists but I don't have it in a public place yet. Note that in spite of what it says in various places on the conference's Web pages, Venkat is the primary author, not me. -Jeff http://www.ncsa.uiuc.edu/SDG/IT94/Proceedings/DDay/mogul/HTTPLatency.html Improving HTTP Latency Venkata N. Padmanabhan (University of California -- Berkeley) Jeffrey C. Mogul (Digital Equipment Corporation Western Research Laboratory) Abstract The HTTP protocol, as currently used in the World Wide Web, uses a separate TCP connection for each file requested. This adds significant and unnecessary overhead, especially in the number of network round trips required. We analyze the costs of this approach and propose simple modifications to HTTP that, while interoperating with unmodified implementations, avoid the unnecessary network costs. We implemented our modifications, and our measurements show that they dramatically reduce latencies.
