If I were the admin of a mirror you used to do speed tests with random 
files, I would not be too happy with you. Speed tests should be done 
with a legitimate file that you *need* -- Perhaps a scoreboard system 
addon would be better to keep track of download speeds from different 
mirrors. This could go along with the region codes and/or mirror weights 
and the addon would adjust according to the [actual] fastest mirror.
