Firefox Performance Settings (from the MozillaZine Forum)

How to: just cut and paste then save to your user.js file (use chrome edit so you don't need to dig into your Documents and Settings/"username"/Application Data/Mozilla/Firefox/Profiles/"default"/user.js)

I tested it and it works! (56K, DSL & Wi-fi Connections tested, but it should speed things up regardless of your connection.)

One of the limitations of pretty much all computer applications is the need to target for a general audience because of the wide array of computer components and varied network infrastructure. This is where tweaking comes in. Firefox by default is aimed at a general audience too and hopefully we can tune it more to the needs of theindividual. The majority of the information comes from this excellent thread over at the MozillaZine Forum. The first post in particular goes through in great detail what each of the settings do. The thread however gets fairly long and convoluted and we attempt to summarize the contents of this thread along with a couple other sources into something that is easier to digest. As with the settings on the previous page, the contents are copied into the user.js file. We do not go into major detail about the setting as the thread goes into detailed explanations of what the settings mean in the first post. Instead, the configurations are culled from the thread of what people have reported to have worked for them along with some modifications on our end.

Quick and Dirty Settings (part of the tweaks further below)

user_pref("network.http.pipelining", true);
user_pref("network.http.pipelining.firstrequest", true);
user_pref("network.http.pipelining.maxrequests", 8);
user_pref("nglayout.initialpaint.delay", 0);

Pipelining does multiple data requests at once and should speed things up. I believe IE did this before and this was partially attributable to the speed advantage that IE had over older versions of Mozilla/Netscape. Initial Paint Delay actually slows down the rendering of the ENTIRE page but since users tend to start reading before the entire page is rendered, setting this to a low value gives the impression that the page loads faster.

The following configurations are based off of recommendations off of the Mozillazine thread with some editing.

These are the settings that seem to be common to all configuration files regardless of connection speed or computer speed with a couple of additions - plugin paths can be found with about:plugins and the bookmark menu delay is turned off.

user_pref("network.http.pipelining", true);
user_pref("network.http.proxy.pipelining", true);
user_pref("network.http.pipelining.maxrequests", 8);
user_pref("network.http.request.max-start-delay", 0);
user_pref("content.notify.backoffcount", 5);
user_pref("plugin.expose_full_path", true);
user_pref("ui.submenuDelay", 0);
user_pref("nglayout.initialpaint.delay", 0);

Fast Computer, Fast Connection:

Definitions:

Fast Computer: is a machine with a CPU greater than 1.5Ghz and with memory installed of at least 512MB RAM

Fast Connection: is a DSL, cable or a better connection

According to the above, 'Slower' connections means slower DSL or cable connections as well as double line ISDN connections, and 'Slow' means all other analog modem connections.



A 'Slow' computer is a computer with a CPU slower than 1.5Ghz, and with less memory than 512MB RAM.



user_pref("content.interrupt.parsing", true);
user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("browser.cache.memory.capacity", 65536);

A couple settings of note - Firefox is allocated 4096 KB of memory by default and in this configuration we give it roughly 65MB as denoted by the last line. This can be changed according to what is used.

Fast Computer, Slower Connection:

This configuration is more suited to people without ultra fast connections. We are talking about slower DSL / Cable connections as well as double line ISDN connections.

user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("browser.cache.memory.capacity", 65536);

Fast Computer, Slow Connection:

Slow connection means connections through an analog 57k modem or slower.

user_pref("browser.xul.error_pages.enabled", true);
user_pref("content.interrupt.parsing", true);
user_pref("content.max.tokenizing.time", 3000000);
user_pref("content.maxtextrun", 8191);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("network.http.max-connections", 32);
user_pref("network.http.max-connections-per-server", 8);
user_pref("network.http.max-persistent-connections-per-proxy", 8);
user_pref("network.http.max-persistent-connections-per-server", 4);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("browser.cache.memory.capacity", 65536);

Slow Computer, Fast Connection:

user_pref("content.max.tokenizing.time", 3000000);
user_pref("content.notify.backoffcount", 5);
user_pref("content.notify.interval", 1000000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 1000000);
user_pref("content.maxtextrun", 4095);
user_pref("nglayout.initialpaint.delay", 1000);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("dom.disable_window_status_change", true);

One of the changes made for this particular configuration is the final line where the status bar is disabled for changing web pages to save processor time.

Slow Computer, Slow Connection:

We have entered the doldrums of the dial-up user

user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("nglayout.initialpaint.delay", 750);
user_pref("network.http.max-connections", 32);
user_pref("network.http.max-connections-per-server", 8);
user_pref("network.http.max-persistent-connections-per-proxy", 8);
user_pref("network.http.max-persistent-connections-per-server", 4);
user_pref("dom.disable_window_status_change", true);
