Mozilla Performace Tuning

[Thing]

I've been goofing with Moz 1.6 today and found some tricks that seem to help out.

1.  Increace the TTL for DNS cache.
The default is 900 seconds.  How often do web sites change their IP address?  Not very!  By increasing this to a higher number, say 86400, you will only need to do a lookup once per day.  By the way 86400 is  the TTL I use for my DNS servers.  To accomplish this, find and edit prefs.js.  Insert or modify this line:

Code Select Expand

user_pref("network.dnsCacheExpiration", 86400);

2.  Decrease the HTTP request timeout.
The default is 120 seconds.  Screw That!  I don't want to wait 2 minutes for something that isn't going to load anyway.  Open Moz and navigate to about:config  Lookey way down in the network section and modify this key:

Code Select Expand

network.http.request.timeout    user set    integer    30
I changed mine to 30 seconds.

Post some of your tips here please.
