Originally heard this posted on the Daily Source code but then found the link since I wasn't able to update it while driving - what a difference. Very easy to do:
In Firefox, put in about:config into the address bar.
Set “network.http.pipelining” to “true”
Set “network.http.proxy.pipelining” to “true”
set network.http.pipelining.maxrequests to a higher number than 4.
It also notes that you should put in
nglayout.initialpaint.delay and set it to 0. (this value is the amount of time Firefox waits before acting).
It's a great performance increase. Try it.
