Speed up Mozilla Firefox about 3-30x Faster !!

There was a article in my google reader related to speeding up the uploading speed of Mozilla Firefox. It was from some Marshal. I treid that but din't experience much out of that, may be as I have lesser speed, so this might be the reason I din't experience that much as mentioned in the article. But I do notice a small change in that. If you feel like trying it, and notice something great out of this please let me know. I am mentioning the steps for you all.

1. Type "about:config" into the address bar and hit return.
Scrolldown and look for the following entries:

network.http.pipelining
network.http.proxy.pipelining
network.http.pipelining.maxrequests

Normally the browser will make one request to a web page at a time.When you enable pipelining it will make several at once, which reallyspeeds up page loading.
2. Alter the entries as follows:
Set "network.http.pipelining" to "true"
Set "network.http.proxy.pipelining" to "true"
Set "network.http.pipelining.maxrequests" to some number like 30. This means it will make 30 requests at once.
3. Lastly right-click anywhere and select New-> Integer.
Name it "nglayout.initialpaint.delay" and set its value to "0".
This value is the amount of time the browser waits before it acts on information it recieves.If you're using a broadband connection you'll load pages 2-30 times faster now.
