    Mas, como sempre, nem todos os testes são fiáveis, e este parece ser um deles (ou a margem é tolerável?).

    Frequently Asked Questions

    1. What is Internet connection speed?

    Internet connection speed refers to the data transfer rate from the Internet to your computer. Basically that means the amount of time it takes your computer to download a given amount of data. Internet connection speeds are usually measured in Kbps (kilobits per second, or thousands of bits per second) or KBps (kilobytes per second). Nowadays with the technological improvements in data transfer speeds, Internet connection speeds can also be measured in Mbps (megabits per second, or millions of bits per second) or MBps (megabytes per second). For example, if you had a 28.8K (28,800 bps) modem, then it would take at least 4 - 5 minutes to download a 1MB file. If you had digital subscriber line (DSL), the same 1MB file would take approximately 10 - 20 seconds.

    2. How did you calculate my Internet connection speed?

    Your Internet connection speed was calculated with 1 or 2 tests, depending on how fast your computer received the first file.

    We performed the first test by sending a 150KB file to your computer and recording the amount of time it took for your computer to receive it.

    If it took your computer 1.0 seconds or longer to receive the file, then the first test calculation provided your final result.

    If your computer took less than 1.0 seconds to receive the file, then we performed the second test. Based on the first test calculation, you were redirected to another Web page with either 600KB, 1.5MB or 3.0MB of data. The time it took for your computer to download that Web page was then recorded.

    Amount of Data = Your Internet
    Connection Speed

    Time to Download

    3. Why were 2 tests performed?

    The second test was performed because sending larger amounts of data to your computer would provide more accurate results for your Internet connection speed test.

    4. If I refresh the page or recalculate the test, will my results improve?

    Not necessarily. The Web pages are not cached by your browser. So each time you refresh or recalculate the test, all files are reloaded as if you were taking the test for the first time.

    5. Why do the results vary each time?

    The Internet is a global network, basically a vast grouping of computers transferring data to one another. Connection speeds will vary depending on many conditions such as the time of day and the amount of congestion on the Internet in general. When you request a Web page from a server on the Internet, both the request and the resulting page travel over a series of links that help comprise the Internet. Points between links are often referred to as "hops." So depending on the number of people connecting to our servers, the number of "hops" taken to get to our site, the quality of the connections between each hop to this site and various other factors, your Internet connection speed will always vary.

    6. I have a 56K modem. Why is my result lower than 56.6 Kbps?

    Your 56K modem has the ability to transfer up to 56.6 Kbps or 56,600 bps. But that doesn't mean that you can connect to the Internet at that speed. There are many factors involved, including the quality of your telephone line, the quality your telephone company's switches, and FCC regulations.

    1º Queres picar, tiras o cuzinho da cadeira e dizes bacoradas na minha cara.
    Qual explicação técnica?
    Muito simples, a thread começou devido ao speedometer acusar velocidades espectaculares (relativas claro). Depois de fazer os testes, apercebi-me que os resultados eram adulterados ou muito incorrectos pelo menos. Daí achei que deveria por o endereço de outro medidor que pelo menos eu aceitei como fiável. Por outro lado também calculo que não tenhas feito os testes e limitaste-te a atacar, ou então, fizeste e os resultados não foram os melhores...:'(

    PS: Essa história do respect não soa lá muito bem
