Hi,
When there is a wow update, the ‘initializing’ phase of the download is very slow. This process uses my internet @ 500kb/s and downloads about 200mb. Then the ‘downloading’ phase starts and uses my full internet speed and downloads a further 150mb, in the case of the latest patch/hotfix being small. Its been like this for a while.
Why is the initializing speed so slow only using 500kb/s when it could/should use the full bandwidth?
The updaters “Initializing” phase is notoriously slow. Has been for a long time now. Like 4 or 5 years.
Blizzard has never explained why its so slow, and probably never will.
The downloading phase can either be slow, or fast, as I believe its torrent based, not CDN server based. Which means you are downloading fragments of the patch files from a lot of other users, not from Blizzard themselves. So your download speed will depend on the number of users with the patch fragments you need, and the speed of their upload.
For me the entire process, including the actual download was super slow. Starting with a few hundred Kbps for the initialization to all but stopping for the actual download. Thinking there was something wrong with my connection I fired up Steam which downloaded updates normally. I have a 1 Gbit connection.
yeah suddenly started having this issue the last few days for all battle net downloads refuse to use my full internet speed unless i turn limitation for speed on and off again for a short while and even then it doesnt stick to using my full speed for long like it used to be able to. right now it is downloading diablo 4 at 6,20 MB/s so it managed to get it out of the kbs range but it is still under the 35 MB/s it should be in
been “stuck” on Initialization for like hour and half now with slow af download 43 MB of it and its like a modem speed…it wasnt like that before
I have been stuck on initializing for almost 2 hours already. Can’t do sh*t, tried everything.
Same, trying scan and repair as we speak, see if that helps
Waste of time 
I did it, took like 20 mins, still the same
Ye, its the same with overwatch, stuck ther aswell, so that sucks
After waiting hours I am downloading now with around 10kb/s…
I really hope they fix this issue
Update is exteremelly slow for me as well - my connection is fast and stable . Please fix this.
I have this today. Closed game, to restart it, Friday evening.
It went close to dialup speed? Well, just above dialup speed. 67Kbps.
And now. initializing 0% of something…
i have this problem too; on my pc and my wife pc ; we have like 50 megabits per second of bandwith for download normally , but blizzard app use to download at less than 1 megabit per second ; we dont have any other app or systems that use bandwith ; we use to get rougly the full 50 Mb/s with similar systems like steam ; at this time we will take hours before to be able to play the game 
I can’t even start the download. It says that my version (10.1.5.50438) is not compatible, but I can’t download any update or patch… it just keeps serching for updates…
