Firefox speed tweaks

[sdageforde]

Try these:

Type in the Address Bar; about:config

Then scroll over to the following settings and adjust:

network.http.max-connections :40

network.http.max-connections-per-server :20

network.http.max-persistent-connections-per-server :20

network.http.pipelining :True

network.http.pipelining.maxrequests :32

network.http.proxy.pipelining :True

Show pictures as they load
user_pref("browser.display.show_image_placeholders", false);


Quick and Dirty Settings

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);


Common to all configurations

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("content.notify.backoffcount", 5);
user_pref("plugin.expose_full_path", true);
user_pref("ui.submenuDelay", 0);

Fast Computer Fast Connection

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 not talking about dial up connections but slower DSL / Cable 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
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);

Some of the options we chose not to include as opposed to sus-per-server", 8);

Cool...Thx SD...I'll try it!

[Tarun]

Then test the results here:

Btw, what would qualify as a slow computer?

Running 800MHz AMD Athlon with 60GB HD, 256MB RAM on cable Internet.

From sdageforde's post I'm getting 9.0 seconds on the test page.

Update: Best results now are 6.901 seconds

An Athlon XP 3200+ 512 MB DDR400 computer with a Raptor 74GB and 10Mbit ADSL+ spins that page up in 1.5-2 seconds using IE. I haven't tested Firefox yet as this is a temporary Windows setup. Will later.

[SiMoNsAyS]

definetly not the best test, check my system at my signature, my bandwidth is 512kbps and using firefox 1.0 tweaked i got from 22.3 to 3.5 sec! ( probably a matter of the browser cache LoL) and using iexplorer from 19.8 to 8.9

[MCT]

wow.. i must kick a** then i got 2.8 seconds on opera lol

[CoffeeFiend]

I haven't bothered comparing (chances are most of what's at that page is already listed here but anyways...) There has been those kinds of tweaks around for quite a while, but I always delayed for v1 final to consider integrating it in my unattended install of firefox

Firefox Speed Tweaks

I'm sure there's lots more floating around on the web too, google could probably find lots

[lotrtrotk]

From that link Tarun posted, I got 2.51 seconds Running Firefox 1.0, on a 2.6G P4, 512mb ram.

Thats without these tweaks (I like the motto, "aint broke, dont fix it"). Just out of curiosity... what exactly do these tweaks change? What is "proxy pipelining"? Considering I don't use a proxy, would this have any effect at all?
