Hi, I saw recently that IE 8 increased their number of downloads per hostname from 2 to 6 [1]. Out of curiosity, I wrote a small testcase [2] to measure what is the default settings in other browsers. The test measures how many persistent connections are opened in parallel to a given server:
Firefox 2: 2 Firefox 3: 2 Opera 9.26: 4 Opera 9.5 beta: 4 Safari 3.0.4 Mac/Windows: 4 IE 7: 2 IE 8: 6 So apparently Firefox will have the smallest default value in the latest major browser versions once IE 8 is out. The real question would be to know if raising that default value is worth it from the user experience point of view. On the other hand, the HTTP RFC recommends only 2 simultaneous connections per server, but as Steve Souders points out: "... the spec was written in 1999. Today’s clients and servers can support more parallel downloads" Sylvain [1] http://www.stevesouders.com/blog/2008/03/10/ie8-speeds-things-up/ [2] http://www.spasche.net/files/parallel_connections/ _______________________________________________ dev-tech-network mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-network
