Choosing the right DNS servers can make all the difference between a fast and snappy web browsing experience and a slow and untolerable one. I came across a utility called namebench, published by Google to test out DNS server speeds. It takes about 5 minutes and could result in a faster web experience - I would recommend giving it a shot. In my case, comcast is the fastest DNS server, so no changes needed to be made, but your environment may be different.
