I've got a symmetrical 170Mbps connection, speedtest around 168/169. I can hit these numbers quite nicely in real life, I just attempted an upload to my google drive and hit 165Mbps for at least 30 seconds.
However, my upload to SharePoint is terrible.
It seems to cap out around 7Mbps for the upload speed. Doesn't matter if I'm using the browser upload, windows explorer, powershell bulk upload, or Sync(OneDrive for Business)
Does anyone get more than this?
I googled and found articles about changing registry values for WinSock rates (no effect) and using Fiddler (no effect)
I'm also going to file a ticket with Microsoft, but anyone have any other thoughts?
