The test ends at the predetermined time, and the client presents your current upload bandwidth in megabits per second. The upload test works in reverse: the client sends test data to the server and takes measurements.

Just click the blue 'RUN SPEED TEST' button to see your download speed, upload speed. The test ends at the predetermined time, and the client presents your current download bandwidth in megabits per second. The speed test results will give you a lot of insight into what is going on with your internet connection. As the client downloads this data, it measures the speed and makes adjustments as necessary-like opening more threads and requesting more data-to maximize the full bandwidth of your internet connection. Next, the client establishes multiple connections (called threads) to the remote server and requests test data. The test ends, and the client presents the lowest roundtrip measurement in milliseconds. The client records the amount of time the exchange used and then repeats the test a few more times. It then sends a tiny bit of data to the remote server, which sends a bit of data back to the client. How does the Spectrum Internet ® speed test work?įirst, the test client on your device determines your location and finds the closest server.
