The target download speed is measured for the HTTP source and Group/Internet peers. The target download speed measures the download throughput available to the source, not only the local network card. A speed test is performed dynamically every few minutes during a download, so it can adjust to congestion on the network. + + Throttling will apply only to downloads from the internet which include the HTTP source and Group peers. To make changes to the default behavior, use the settings from the Delivery Optimization section in Windows Settings (Delivery Optimization -> Advanced Options) to change these values. In addition, there are policies available to manage bandwidth usage for Delivery Optimization. To ensure smooth deployments, we recommend familiarizing yourself with the bandwidth defaults and policies available to better configure them for your environment.
