Slow Blizzard games download

[RobertJamesMichael]

Hi, I am testing the speed, Blizzard is downloading very slow on "new" downloads, about 500 KB/seg on a 100 Mbit connection, I tested riot and the download speed is ok, any suggestion? thanks for your time!

Try giving the cache server multiple ip addresses, and make the dns round robin between them. That might help increase the parallelism. Find out which cdn server it's downloading from, ping it, and see how far away the cdn is in milliseconds. And then check the nginx logs to see how large the downloaded chunks are. There's an issue with the way nginx works that means high latency connections downloading small chunks will be significantly slower. I have a thing I was playing around with to fix this, but I haven't released it yet.

Thanks @sirsquidness, I am using 10 IPs, I am using a physical router as DNS server also, I would like to change it to a Linux (Ubuntu) based one, which one may I use to make this "round robin" work better? The dnsmasq docker image you have in this project does make the work?
I am testing with WOW and its been downloading from level3.blizzard.com, it's about 120 - 130 ms far away.
and this is a portion of the Blizzard access log:
