I have just come across this little Firefox 'tweak':
Firstly open Firefox, then in the address bar, type in about:config Start by finding 'network.http.pipelining' and double-click it to read true and then do the same for 'network.http.pipelining.maxrequests' and change the value from the default of 4 to 10.
Finally, find the 'browser.turbo.enabled setting' and double-click on it to change if from the default false to true.
Firefox should run a bit faster now. Apologies if this has been posted before!
You can do the same thing in IE, download managers and other apps. I prefer to leave them at default values as otherwise it does put additional strain on servers, and I don't feel I need the additional speed. Not being preachy, just my point of view.
"Internet Explorer 4, 5 & 6 have been designed to comply with Hypertext Protocol 1.1. This dictates that a web browser should draw no more than two stream of data at any one time. However, your browser is capable of getting many more times that, and so if you were to increase the number of streams that it is looking for, you will vastly speed up the whole process."
