(Geek factor: high)
I recently bought the book
Hacking Firefox (for those who don't know, Firefox is a web browser which is much more customizable than Internet Explorer, IMHO of course). I tried some of their performance enhancements and WHOA! It's like I've gone plaid and running at ludicrous-speed...
Here's what I added to my user.js file
user_pref("network.http.max-connections", 96);
user_pref("network.http.max-connections-per-server", 32);
user_pref("network.http.max-persistent-connections-per-proxy", 24);
user_pref("network.http.max-persistent-connections-per-server", 12);
user_pref("network.http.pipelining", true);
user_pref("network.http.proxy.pipelining", true);
user_pref("network.http.pipelining.firstrequest", true);
user_pref("network.http.pipelining.maxrequests", 8);
user_pref("network.dnsCacheExpiration", 86400);
user_pref("network.dnsCacheEntries", 256);
user_pref("network.ftp.idleConnectionTimeout", 60);
user_pref("network.http.keep-alive.timeout", 30);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("content.notify.ontimer", true);
user_pref("content.interrupt.parsing", true);
user_pref("content.notify.interval", 100);
user_pref("content.notify.threshold", 100000);
user_pref("content.notify.backoffcount", 200);
user_pref("content.max.tokenizing.time", 3000000);
user_pref("content.maxtextrun", 8191)
If you wish to try it out on your Firefox and need some help, let me know.
