Speed up Firefox
« on: January 01, 2008, 12:33:49 AM »

I came across this some time ago but resurrected it for a post elsewhere, I thought it may be of use to some members on here. 
How To Speed Up Firefox
From:
http://www.freerepublic.com/focus/news/1299854/posts

1.Type " about:config " into the address bar and hit Enter. Scroll down 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 really speeds up page loading.

2. Alter the entries as follows by double clicking on each one if it is not reading as below:

Set " network.http.pipelining " to " true "

Set " network.http.proxy.pipelining " to " true "

Set " network.http.pipelining.maxrequests " to some number like 8 . This means it will make 8 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 MUCH faster now!

Well I've done it and it does seem to be a bit snappier. Thanks Dave. :)

>>> Set " network.http.pipelining.maxrequests " to some number like 30

This really isn't a good thing to do. Each request is like an extra user connecting to a site, and if lots of people were to use this tweak it would quickly clog up sites, slowing them down for everyone. It drives the admins of web servers mad, and you may find it drives Kitz mad when she emerges from her New Years Eve hangover. :)

Set " network.http.pipelining.maxrequests " to some number like 30 . This means it will make 30 requests at once.

My own Firefox tweak notes recommend 8 for this value; the default is 4.  Could someone (e.g. Eric) give an informed opinion on this one?

8 is the highest value allowed by web standards, and is also the highest value recommended by mozilla.org.

After seeing at least a couple dozen blog posts all referencing these changes to "speed up Firefox", I thought it would be worth a little explanation.

Yes, enabling HTTP pipelining can dramatically improve networking performance. The downside, and the reason it's not enabled by default, is that it can prevent Web pages from displaying correctly. If you've enabled this, and you find pages that aren't displaying correctly, please don't blame Firefox or the Web developer. It's probably the fact that you enabled an "unsupported" feature which is incompatible with some Web servers and proxy servers.

The second change, setting the initial paint delay at zero, may get you some content on the screen faster, but it's worth noting that it will dramatically slow down the time it takes the entire page to display. Here's what's going on. Gecko, Firefox's rendering engine, is trying to optimize between the cost of waiting for a bit more data versus doing more painting and reflows as new data comes in. Waiting a bit longer before it starts painting the page gives Gecko a chance to receive more content before chewing up CPU cycles to render and reflow the document. If you drop this value down to zero or near zero, that means you'll see the page start displaying a bit earlier, but not having received much data in that short interval, you'll have a lot more paint and reflow cycles to complete rendering of the page.

So not much point setting it at 30 anyhow - maximum is 8.

Indeed. I'm pretty sure you're not going to find many proxies that like even 8 concurrent requests though so I'd be inclined to turn the proxy pipelining off even if you leave http pipelining on.

I'll try turning proxy pipelining off too. :)

Now how about the value for network.http.max-persistent-connections-per-server - I note that mine has a user set value of 22, but I don't recall modifying it.  What would be the optimum value?
