The test is performed with cache prevention via random strings appended to each download.

Based on this result, one of several file sizes is selected to use for the real download test.

Small binary files are downloaded from the web server to the client to estimate the connection speed.

This test is performed by measuring the time it takes to get a response for a HTTP request sent to the web server.

During the first half of the test, the client will establish extra connections to the server if it determines additional threads are required to more accurately measure the upload speed.

As the chunks are received by the server, the client will send more chunks throughout the duration of the test.

The client calculates the real-time speed of the transfers and adjusts the chunk size and buffer size based on it to maximize usage of the network connection, and requests more data.

The client establishes multiple connections with the server over the defined port and sends an initial chunk of data.

The test ends once the configured amount of time has been reached.

The client establishes multiple connections with the server over port: 8080.This test is repeated multiple times with the lowest value determining the final result.The round-trip time is measured is measured in ms (milliseconds). The client sends a message to the server, upon receiving that message, the server sends a reply back. This test is performed by measuring the time it takes for the server to reply to a request from the user's client.

measures ping (latency), download speed and upload speed.

In addition, we can use the Android or iOS location services to determine a more accurate location operates mainly over TCP testing with a HTTP fallback for maximum compatibility. If you're using one of our mobile apps, this process all happens in the background before you press Begin Test.

(For more information, you can read our article on the full testing methodology used on .) We can then begin the full test process: measuring your ping, download speed, and upload speed. This is the server that's 'closest' on the network, and usually provides the most accurate results. We then ping those nearby servers, and choose the server with the lowest result, meaning it took the shortest time for a response. Once you press Begin Test, we take your location and determine up to five nearby servers (using spherical geometry). After loading the list of 1000+ servers and the appropriate map tiles, we can display the map of hosts on the front page. This tells us where to center the map-but more importantly, it also tells us which servers are nearby. The first step begins before you even press the button: we look up your IP address in a GeoIP database to determine your approximate location.
