Ok so if i say the letters DNS most people will probably stop reading so i will put this in to plain old english. the internet works using numbers and every website has its own number. like a house number. when you type a web site address your computer looks in a phone book finds (say wikiwirral) and finds out what number it lives at on the internet.
This service is called DNS and there are many of them, like yell, Thompson and the BT phonebook. the chances are the one that you use (your service provider (BT, Sky or Virgin) isn't the fastest one for you to use.
Download and install a program called namebench (its a free opensource utility held on google servers) this will take about 5 mins and it will run through searching all the DNS servers and finding out which one is the quickest for you and it will tell you by how much.
I just ran mine and i have improved my lookup speed by 75%. not a bad increase if i say so myself.
