For the second time now i the last couple of months I have experienced the “initializing” taking 1 hour for a few hundred MB.
I have tried to delete Battle.net-files etc.
“It do be like that sometimes” is the only response I see on similar threads, and that is not good enough. It should not be like this.
I have 500/500mbit/s connection, and optimized settings for P2P-traffic, and no issues with speed with other downloads.
The installation is also on a separate SSD than the OS, and no stuff running of it, so I know this is solely the Battle.net-client.
Why does this keep happening? Extremely annoying being an hour late to our raid every now and then.
sorry for late reply, however I had this ridiculous slowness as well, and mainly even if I re-installed my pc from scratch, the issue persisted.
As preamble, note that my Internet connection is a gigabit connection (1000 Mbit download / 100 Mbit upload).
On trying to understand the issue on my own, I found out that the Bnet client, when downloading content, was eating all bandwidth of my Internet connection (my pc is wired to my router), resulting that I wouldn’t be able to surf the web, watching streaming services (like Netflix) or do a simple download on the same pc as the Bnet client is running, or any other device I have at home.
Nonetheless, the download speed of the patching/game re-install was a mere 300KB/s.
Also tried with another pc with same results, as soon the launcher starts a download, the Internet connection wasn’t usable in any other devices, either wired or wireless.
In normal circumstances, like download a game/patching from the Steam client, I see I can reach easily 90MB/s (yes megabytes per seconds), which translates well for a gigabit connection to the Internet, also note, that other devices at my home, are able to surf the web/doing online stuff.
So this led the culprit to the Bnet launcher only.
So, how did I resolved my issue? Simple enough, I set a limit on the download speed on the Bnet client. In my case, I specified a limit around my Internet connection max speed, and this resolved the slowness to patch/download games and the bandwidth clogging for all other devices. Also the download speed of patcher/game re-install, did skyrocketed to a normal behaviour (somewhere like 50MB/s).
Just go in the Bnet app settings, and specify the download speed limit (if I recall correctly, it is listed in kb/s so I set in my case 80’000kb/s for either game and pre-patch content).
In your case, I would suggest to set this limit at around 50’000kb/s, which result in downloads around 50MB/s. But of course you’re free to play with the setting yourself (word of caution, do not exceed your maximum bandwidth, or you will face the same issue).
