Use the speed test to measure the upload and download Internet speeds between the computer on which you are running the test and this monitoring server. The monitoring server is located on the Datastream backbone.
This test consists of a file download from the IHMS server to your PC. By calculating the time taken for this download to be completed, the server can calculate your upload and download speeds at that particular moment in time.
The upload speed refers to the speed of the connection from your PC to the IHMS server. On the other hand, the download speed refers to the speed of the connection from the IHMS server to your PC. Usually an Internet connection is not symmetrical and the download speed tends to be higher than the upload speed, for example 128k (download) / 64k (upload) connection.
