Cisco Umbrella provides a couple of downloads for testing performance of the Network Tunnel. These files exist in every data center and can be used as a good performance measurement for determining the average download speed for a real file download. They measure the performance of the customers' tunnel and Umbrella infrastructure without additional overhead of the connection between Umbrella and a third-party website.
Downloading the Files
You can download the files using a tool which measures the average speed. Here is an example using curl which prints progress by default:
curl http://188.8.131.52:8080/target-10M -o /dev/null
Testing CDFW Only:
Caveats for Downloading
- These files are provided "as is" without documentation or support for testing.
- Disable other Anti-Virus and web security software (including Cisco AnyConnect) when testing this
- Disable other on-premise web security solutions (proxies, URL filtering) when testing this
- The performance may be affected by other concurrent traffic this customer is generating.
