Network devices, like routers and switches, can then use the DSCP value to classify network packets and queue them to control bandwidth usage. Implementing QoS to protect upload bandwidth involves assigning a differentiated services code point (DSCP) value (0-63) to network packets generated by the OneDrive sync app and then limit the maximum upload rate that the app can use. Users can either change the settings manually or they can be configured using Group Policy or registry settings.

But for users on home networks, it’s more practical to configure the network utilization settings in the sync app. Microsoft recommends using network quality-of-service (QoS) policies as the best way to manage network utilization of the OneDrive sync client.

It’s useful to establish a benchmark so that you can better troubleshoot connection issues when they occur. To understand the actual bandwidth obtainable from your Internet service provider (ISP), make sure that the network isn’t being used by other applications or devices when the test is running. To check the available upload and download bandwidth available on your network, you can use a service like. This in turn causes a sluggish response when loading websites on devices connected to the local network. In this case, large files that need to be uploaded by the sync client can quickly saturate upload bandwidth. The faster the OneDrive client can upload files to the cloud, the quicker they are available for sharing or to access from other devices.īut as more of us are working remotely due to the global pandemic, the available upload bandwidth at home is often much lower than download bandwidth. The default upload setting may even be an advantage as you can be sure any documents which are saved to locations synchronized to OneDrive will be uploaded to the cloud quickly. If the client is synchronizing small office files, or there’s a large amount of upload bandwidth available, then the default setting might not present a problem. In other words, it can saturate your upload bandwidth.
