Internet Speed & Latency Test

What is a speed test?

It is the fastest and simplest way to measure the speed at which your ADSL line browses. This way you will know the upload and download speed and you will be able to know the efficiency of your connection.

It is important to do a speed test to measure the download and upload speed of your connection especially when you notice that the pages take a long time to load or your P2P programs do not download to the download speed you're used to.

How Our speed test works.

It consists in knowing how long it takes our connection to download a file. In order to perform the calculation, when the speed test starts a file is uploaded to our servers and through a script we measure and calculate the time that our connection has needed to perform the action.

The speed test that we recommend is a free bandwidth test with servers located all around the world.

Advice before doing the test

For the results of the speed test of our ADSL connection as reliable as possible we have to do a number of checks:

  1. We need to check that we don’t have any program using our ADSL connection since it would affect the speed test results…. Download Managers, P2P programs as popular as Jdownloader, Ares, Utorrent, Emule and similar. Mailers: Outlook, Thunderbird,... Instant Messaging: Gtalk, Skype, Messenger (RIP), etc.
  2. Close other tabs in the browser, you might have a page in other tabs that consumes bandwidth.
  3. Make sure you do not have other applications like Dropbox, Logmein...
  4. Turn off or disconnect all the other computers, tablets, phones, thus you will have all the bandwidth of your Internet connection to carry out the speed test and so the results will be more reliable.
  5. Check that your PC is NOT doing online updates of antivirus or installed programs.
With these steps you ensure that the test is more reliable and if the result is not right, you can call your operator company to know why your connection is slow.

How do we interpret the results of the speed test?

If our speed test is 80% of our theoretical connection the result is excellent. If you get a score of 16000 kbps downstream and 800 kbps upstream, you're a lucky, because the national average of 20 meg ADSL2 + is 43%, so if you get more than 8600 kbps download speed results you would have superior results than the national average, Are you feeling better now knowing this?.

The result shows the maximum download speed that has been able to sustain your connection for at least one second. The upload speed indicates how fast you can upload files to the network. Ping or latency is the time it takes to send and receive responses. Less is better.

The velocity curve starts from zero and tends to stabilize in the first few seconds. The flatter, more stable the connection is. The cable or ADSL connections should draw a flat graphic, whereas the mobile Internet access fluctuate. If the speed graphic is very irregular and contains large jumps, the test is likely to be invalid.


Considerations before complaining.

Before calling technical service you should check if any of these points can solve your problem:

  1. If you use a (WLAN) wireless router, you should verify the location of the device, with windows, it's easy to check the quality of the reception. In the taskbar (bottom right on the screen) there is a symbol that shows the signal strength the computer is getting. Sometimes, slightly turning the router or its antennas help.
  2. One source of problems may come when the router is located near the base of a cordless phone, multiple wireless networks slow each other down.
  3. Check that the WLAN is not the cause of transmitting or receiving speed problems. Perform the speed test connected by the Ethernet cable.
  4. Another potential slowdown in ADSL cause may be a defective or outdated splitter. The splitter is a device that separates the voice data of the Internet in several signals, each with a different frequency, and can be easily replaced, do not discard this possibility, it is more common than you think.
  5. Operating systems like WindowsPrevious to XP with Service Pack 2 dos not support more than 6 MBit /s in their default settings. The corresponding changes in the settings can be done easily with DrTCP, this is a free tool available online.
  6. If your modem is old, you should verify that your device supports the ADSL2 + norm, this norm, that do not offer all Internet providers, ensures that the ADSL modem can work with up to 16 MBit / s. ADSL2 old technology only supports up to 8 MBit/s.

Reliability of the ADSL speed test?

If you hire a 20 mega download speed, I guess you would wait for your results to be 19 and 18, I will not say 20 Megs, but the truth is that it is not possible for the many reasons you get from internet providers, distance of control unit number of connections ..., so given that the Ministry of Industry does not guarantee 80% of the ADSL speed as requested in the Users Telecommunications Bill of Rights, you could be happy if the speed test gives you a score between 60 and 80% of the maximum speed of contract, that is, for those 20 mg’s your result should be between 12 and 16 megawatts. If you get less than that you should start thinking about changing supplier, because if your score is 10 mgs or less you could hire a 10 Meg line and pay less depending on the provider the course.

The speed test result does not show 100% of the connection speed, because the results are influenced by several factors as we mentioned before, distance to control unit, the status of your line noise / signal attenuation, interference or even server load, but the result of these speed test gets very close to the actual speed of our ADSL connection results.

At the end of the analysis, we can check the download speed (important in file sharing programs, P2P) and upload speed which is what allows us to send files or emails.

The result is shown in kilobits per second, wich is a unit of measure used in telecommunications and computer to calculate the speed of information transfer across a network.

The performance of a connection will never be 100%. Bear in mind that in these types of connections (analog modem, ISDN, ADSL, etc.) use various protocols (PPP, TCP / IP) that occupy bandwidth (between 2% and 20% of the 100% of the total, depending on the type of connection or the protocol used), thus the bandwidth usable for downloading data is reduced. The results shown in this test correspond to the usable bandwidth, IE, this equates to the speed of information transfer, and not to the access speed. In addition there are other no measurable factors that may contribute to reduce the speed of the connection, such as congestion in the network, electromagnetic interference, etc... which also influence the final result.
