Here is a little tool google provides for increasing your internet speed. This tool shows you how much time it saved... for me it has saved 2.2 hours so far Take a look http://webaccelerator.google.com/
But there are some privacy issues relating to it http://www.google.com/search?q=goog...avclient-ff&ie=UTF-8&rlz=1B3GGGL_enIN253IN254
With 3 Mbps I don't need any faster internet but it's cool tool if you don't mind Google spying on you.... p.l.u.r.
Dial-up users may not see much improvement, as Google Web Accelerator is currently optimized to speed up web page loading for broadband connections.
