Select a faster mirror server for Ubuntu

I am installing a VM on my Vista. And I install an Ubuntu 9.04 on this VM too. Choosing a fast mirror server is very import for our work. Recentlly, I read a blog from http://www.ubuntugeek.com/how-to-select-fastest-mirror-in-ubuntu.html . This is a very great artical. Works very well for me. At first, I use the default mirror server in China. The network is bad, the downloading speed for package is about 10KB/s. Now, the speed became 50KB/s ,even more.

This simple procedure works very well for me. I suggest that you should have a try.
