[Bug] Download speed wrong


i noticed that there is a bug with in the Battle.Net app. The download speed can show numbers that do not reflect the reality.

I had a problem where my Battle.Net app would only download for around 1,23 seconds after starting the download. I then had to pause/play trough the whole patch. The Battle.Net app always showed 30MB/s while my Task Manager, AIDA64 and NIC monitoring reported very different numbers (like 7kbs so no download). How is this possible? Should the download speed indicator not indicate the actual download speed? Why and how does it calculate a speed of 20MB/s when it is actually 0? Can you please explain on how this number is being calculated and the technique used to compute it?

Best Regards,
