I read on AskDaveTaylor.com that tweaking a few Firefox config settings will speed it up. Specifically, he
says that setting network.http.pipelining, and network.http.proxy.pipelining to true, and network.http.pipelining.maxrequests to 20 will do the trick. Has anybody had any luck trying any of these tweaks?
Dave Taylor also recommended reading the following forum on mozillazine.org
There is varying opinion on this “tweak.” I changed mine to 10, saw intermittent improvement. According to the Firefox site, the server has to have pipelining turned on and configed properly for anyone to gain anything. Simply put, YMMV.
