I found these tips on speeding up Firefox here, and it does seem to speed it up significantly even on broadband. However, a couple of the flags (I suspect) refer to older Firefox versions than what I’m currently running (2.0.0.12). Here are the ones I set in the “about:config” screen:

• network.http.max-connections: 48
• network.http.max-connections-per-server: 16
• network.http.max-persistent-connections-per-proxy: 8
• network.http.max-persistent-connections-per-server: 4
• network.http.pipelining: true
• network.http.pipelining.maxrequests: 100
• network.http.proxy.pipelining: true
• Creating a new integer value:

  nglayout.initialpaint.delay: 0

I guess my only question at this point is (a) how much these settings increase the load on web servers and (b) whether these are changes that should really be made. It seems like most of the boost same from the last new integer value, if anything at all sped it up, since painting is now nearly instantaneous. All the other flags do is increase the number of connections the browser is allowed to make (and how it’s allowed to make them, if I’m understanding the pipelining setting properly). Is there any documentation on about:config values?
