The ADSL speed tests are useful to verify, actually, how much difference there is between the speed promised by the connection provider and the real one.
These tests have a dual purpose: to find the best provider to have fast internet and to check if you are paying the right amount or if you can ask for immediate withdrawal due to an unsatisfactory service.
However, what is not very clear is what these ADSL tests are measuring and why there is so much difference compared to the speeds declared in advertisements and in subscription contracts.
To understand ADSL tests it is important to understand how internet speed is measured .

Internet speed tests are measurements of how long a certain amount of data takes to travel between a test server and the computer.
Based on the size of the file and the time it takes to get to the computer, the test calculates the download or download speed.
The size of the file and the time required to pass from the computer to the server, thus making the reverse path, determines the speed of uploading or loading data.
Usually the download speed is higher than the upload speed because the use of the internet more often involves downloading rather than sending data from the computer.

The most popular and reliable ADSL test in the world to measure internet speed, which also works well in Italy is Ookla Speedtest .
Speedtest.net allows to check the internet speed in a very simple way.
More than 50 million people use it and allows you to create an account, save the results to compare them over time in evaluating the ISP.
The site also allows you to make a judgment on your internet provider and to compare the results of the ADSL speed tests of other broadband providers in the area.
The only thing to watch out for in Speedtest is advertising that opens a banner in a new tab that needs to be closed to return to the measurement site.
A similar site is SpeedofMe, which has an excellent HTML5 online tool to measure the internet speed in download and upload, in a very reliable way and with a performance graph.
Another very valid site promoted by Netflix is Fast.com to measure the maximum download and streaming speed and the Sourceforge test which also allows us to know the quality of the internet connection, with the test of the lost packets.
Because the download speed is much lower than what is promised by the provider "> difference between megabits and megabytes.
The speed of a network is indicated using bits per second abbreviated bps (bits per second)
The networks were originally so slow that their speed was measured in only bits.
With the improvement of network technologies, we have gone from bits to Kbps kilobits and then to Megabits Mbps or Mb / s (megabits per second) of modern broadband DLS.
What is confusing is that some programs measure the data transfer rate in bytes which is worth eight bits in length.
A provider can therefore write that the internet speed is 40 Mb / s understood in BIT, while in Megabye it is 5 MB / s (note the capital B).
Basically, if Telecom or Fastweb or Tre or Vodafone say that the connection is 20 Mbit / s, calculated that 1 Mbit = 0.125 Mbyte, (20 × 0.125) = 2.5 Mbyte / s.
In practice, the value to be kept as a reference for the download and upload speed is 2.5 Mbyte per second .
Unfortunately, the real speed will never be even so high and in fact, few are able to download at that speed.
This slowness is due to numerous factors including:
- Problems with an old router.
- The distance from the provider's control unit.
- Congestion of the provider or how many people are connected at the same time (at night it will be faster).
- Throttling or if the Internet provider slows down (or "chokes") certain types of traffic, such as peer-to-peer traffic from programs such as Emule or Torrent.
- Server-Side problems or the site from which you are downloading.
So in the end if you download between 300 and 900 Kbytes per second I would say that, in Italy, we are lucky .
Finally, in Italy there is an official internet speed measurement tool for the suppliers Telecom, Alice, Fastweb, Infostrada and others.
AGCOM, the authority for communications guarantees, provides official software to measure the internet and actually check if it is too slow compared to what was promised during the activation of the contract with the provider.
This official data can be used to make a complaint and, if necessary, also to withdraw from a contract or a subscription.
The program is called Ne.Me.Sys (Network Measurement System) and can be downloaded from the website Misurainternet.it for Windows, Mac and Linux.
To download the program you need to fill out a form with all the personal information, very boring that made me want to go.
