Speed tests measure how fast the raw amount of information can be transferred between the source and destination at the time they are run. In reality, conditions could be very different a short amount of time before or after the test is run.
Internet service providers typically publish upload and download speeds to describe the size of the connection to the home. The test itself is not a real-world measure; actual user traffic rarely uses the connection this way. Thus it is very rare, if ever, to actually get the published speed when using the network.
Speed tests identify a server, typically not far from the source, and send multiple large samples of data to it and then back from it. The data is significant enough to extend beyond the capacity of the connection in order to measure the time it takes to move all the information. It is similar to trying to see how many cars can move on a highway by sending a lot of cars on it until all lanes are full. Clearly, not something that should be done too often because it saturates your network.
Most applications (other than large multi-threaded file uploads and downloads) do not push the boundaries of this measurement and therefore, while useful, are not the only test of internet performance that is relevant. Most video applications, adjust the rate of transmission of packets to a comfortable speed to give the best user experience. As long as there are no other issues, most modern connections have more than sufficient bandwidth (in spite of the attempt by some internet service providers to convince subscribers otherwise).
The monitor-io service sends a small number of packets, in a planned sequence, to different destinations to measure performance. The packets are analyzed in a detailed fashion to extract the precise cause of poor performance. It is the equivalent of sending one car to see if the road is congested, and documenting the issues seen by the car. By sending packets to different points on the globe, monitor-io has a better sense of the performance across different paths and provides a more real-world view of how any end-user would experience network performance.
The device that runs the monitor-io tests is tuned to perform only this one function and is independent of any interference from other applications, thereby guaranteeing accurate measurements. When the device is connected directly to the first router on the premises, it will give the most accurate view of the performance of the internet service provider.
The service keeps track of all this data so that a user can get a historical view of the quality and reliability of their internet service. It also alerts them if there is impaired or degraded performance at any time of the day. In fact, if they do want to do a standard bandwidth speed test, monitor-io allows them to run one from directly within our site as a sanity check...but we believe that our 24x7 lightweight test sequence will be much more useful.

In other words:
- some measurements measure the capacity of a link between a source and destination by flooding it with data using multiple streams etc. (e.g. perfSONAR),
- or may flood a single stream for 10 seconds( NDT)
...
- ,
- many regulatory and governmental bodies around the world, use physical equipment to constantly measure the maximum speed available on particular lines across a long period of time, and it is from this it will derive its average,
- Ookla filters out the slowest 30% and the fastest 10% speedtests.
- Some year-on-year speed changes could potentially be down to factors not connected to speeds in real terms. For example, if new M-Lab test servers were activated closer to or inside of the country being measured (where they had not existed previously), this could show as a speed rise, yet the speeds experienced by citizens may not have subjectively changed.
- Since PingER has fixed MAs this is not a problem for PingER
