This setting lets you balance the performance of different upload tasks on a computer by specifying the percentage of the computer's upload throughput that the OneDrive sync app (OneDrive.exe) can use to upload files. Setting this throughput as a percentage lets the sync app respond to both increases and decreases in throughput. The lower the percentage you set, the slower the files get uploaded. We recommend a value of 50% or higher. The sync app periodically uploads without restriction for one minute and then slows down to the upload percentage you set. This pattern lets small files upload quickly while preventing large uploads from dominating the computer's upload throughput. We recommend enabling this setting temporarily when you roll out Silently move Windows known folders to OneDrive, or Prompt users to move Windows known folders to OneDrive to control the network impact of uploading known folder contents.
