Although I didn't think I'd have to, I actually ended up tweaking Mozilla's Firefox browser
a bit for speed. This page is intended to document that, as well as offer tips for
those who use other browsers.

Mozilla Firefox Tuning

Assuming you've followed the WebCacheProxyTuning page, and have everything up and running,
here's what I've modified within Firefox for additional performance.

First, open your browser and enter "about:config" as the URL. This will access Firefox's
internal settings. Click through the "please be careful" warning, then simply change the following:

Enable HTTP Pipelining

I did some research as to why this isn't enabled by default and really couldn't find any good reasons.
Apache Traffic Server supports this, and I got a roughly 100% speed boost by enabling it.
I also dropped the folks at Mozilla a line and suggested they support this.

network.http.pipelining user_set boolean true
network.http.pipelining.aggressive user_set boolean true
network.http.pipelining.ssl user_set boolean true
network.http.proxy.pipelining user_set boolean true

Increase Connections

As it turns out, this first setting is artifically low on the presumption you'll be using a public proxy
on the Internet and that it's "bad etiquette" to send such a server too many connections.
Being that I'm not going to kick myself off my own proxy server, I went ahead and changed this.

The second setting allows for more connections per server, with the assumption ATS will process these in parallel.

network.http.proxy.max-persistent-connections-per-proxy user_set integer 256
network.http.max-persistent-connections-per-server user_set integer 128

Speculative HTTP Parsing

This setting I've had no end of annoyance finding documentation for.  I found I got a considerable performance boost with ATS by disabling this feature.

network.http.speculative-parallel-limit user_set integer 0

That's it. Go ahead and restart your browser just to be safe, then enjoy your increased surfing speeds.

NOTE:  There are actually additional settings I've modified on both my OS and within Mozilla Firefox itself to get even more performance out of my setup.  I've decided for now not to document them as I'm not sure whether anyone could really use them.  Please contact me on the ATS users mailing list for more details if curious.
