Tech: Goosing Firefox Performance

Got the following tip from a friend this morning, and it does seem to help some, especially on ESPN.com:
Assuming you use Firefox for your browser, follow the simple steps detailed below and you will be surfing the web much faster than before.

  • Type "about:config" into the address bar and hit return
  • Scroll down and look for the following entries and alter appropriately
  • Set "network.http.pipelining" to "true"
  • Set "network.http.proxy.pipelining" to "true"
  • Set "network.http.pipelining.maxrequests" to a number like 30. Firefox will now make 30 requests at once whereas before it would only make one request at a time.
  • Lastly right-click anywhere and select New -> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0" (time the browser waits before it acts on information received)
That's it, you are done, type in your favorite website and surf at speeds previously hidden from you!
Mozillazine says the largest acceptable value for network.http.pipelining.maxrequests is actually 8, so the author of this anonymous piece is likely wrong about the 30 number. It also adds the following caveat:
Higher values will cause a delay before the first request completes but will make the last request complete sooner. Higher values will also cause more of a delay if a connection fails.
The default is 4, so take it for what it's worth. From experimentation, settings of 4 or 8 were indistinguishable from 30 using Flash-heavy ESPN.com as a baseline.
