I make two lines under this argument!!!
Like shboom said: Practice, practice, practice,...
But don't forget the fun while playing. Make your own songs and try to play what your imagination shows you. And if you plan to run faster with your fingers then it's a good tip to look away from your fretboard because of you will learn to play with your feeling only.
The faster you play the faster you have to control your fingers. Once a time you will reach the point where your mind can't registrate the pictures from the eyes as fast as you'll need for coordinating your fingers. So you can control your fingers only with the sense of the finger's touch on fretboard.

And like Pose said, this will be the point where you will see the fretboard in front of your closed eyes...
