one drive syncing is too much slow

We're also experiencing immensely slow upload and download speeds using the OneDrive client, both for Mac and PC, but especially for Mac users. Tested both on and off our VPN client, as well as in numerous Internet configurations (at home, at work), WiFi and cable. Internet connectivity tests shows good speeds (>50MB/s, all the way up to 300MB/s), but still, OneDrive takes forever to even upload a couple of kilobytes in a Word document. This has serious implications as it severely impacts the speed at which we can work with and share files. For example, I just created a 637 kb Word document that I uploaded to my OneDrive for Business that I wanted to share with some colleagues over Teams, document is saved and closed on my computer, no one else has it open, but still, the document takes forever (several minutes) to upload.. 

netadmin37 I have heard this solution before, but as far as I understand from the "Disable Files on Demand" feature, all your synched folders are then downloaded to the local harddrive. This is obviously not a solution if you have three different SharePoint sites synchronized with several hundred Gigabytes, along with your personal OneDrive with 10's of GB stored. I can't be assumed to go buy a 1TB Macbook Pro just for OneDrive to work on my computer, right?!
