This is running on a Windows 7 x64 windows on a Core i7 with 24GB of Ram and SSD's for hard drives. I've completely uninstalled my AV, and the windows firewall is completely disabled (I own an enterprise class firewall, so it is not needed anyway).
My onedrive client (onedrive.exe) says version: Version 2015 (build 17.3.6390.0509), and its only syncing our business data (I don't have onedrive for home).
I am trying to sync ~3000 files for a total of 3.2 GB, so far after 4 hours, I've uploaded only 363MB.
This is absurd.
Before someone from Microsoft responds with a canned message, yes I've read your article Maximize upload and download speed . It is a useless article (and a bit of a cop-out response).
Please admit to your incredibly slow speed, and then proceed to fix the actual (and obvious) network problems you are having at sustaining fast speeds across your onedrive storage network.
