    interesting test! although not sure how you did it. Did you ping their sites and assume that their website was served on their content delivery network? or did you have accounts with all of them and served a common video and/or image file? hopefully it is the later!

    Many ISP’s or Operators do not see value in investing in CDN and the Torrents are having a free ride on the network. If we could find a way for end-user to pay for Torrents then the operators will see value in investing in CDNs. I have suggested asymmetric billing strategy to make end-user pay for Torrents. Hope this will help in widespread use of network based caching as against client-based.

    I think this is critical to understanding the results you have posted. Could you enlighten us?

    [...] do so great. It is really hard to objectively quantify the performance of the various CDNs, but here is one attempt. Maybe I’m being unfair to SimpleCDN here, but they wouldn’t be my first [...]
