Firefox 3 turbo speed optimisation

Following on from my previous article, Firefox 3 Easter Eggs, I have discovered that broadband users can get a significant speed increase from Firefox just by changing a couple of settings.  Firefox is distributed with settings that will work with any machine or setup, but really anyone with a half-decent connection can make these changes and get a great speed increase, and here’s how you do it!

Inside the address bar type:


and then find:


and set them both to “true”.  This adjusts the pipelining settings. Then find


and set it to 8, though you should feel free to play with this number a little and tweak it as you see fit - the article http://kb.mozillazine.org/Network.http.pipelining.maxrequests suggests that 8 is easily sufficient.

Finally, right-click on any setting and select ‘new’ and then ‘integer’.   Set the name to “nglayout.initialpaint.delay” (you might want to copy & paste it) and set the value to “0” (zero).  This removes the render delay.

And hey presto you should notice a significant speed increase from a simple optimization!
