FAQ - speed.io

Questions:


At what should I pay attention before using the speed test?
Before starting the speed test you should take care, that no other internet activities take place like download, messenger (skype, msn, yahoo), e-mail client, FTP connections, P2P etc. If you share your internet connection with other users, please pay attention, that during the test nobody else uses the network, because this can influence the results in a negative way. If you are connected wireless over WiFi (wireless LAN), you should place yourself as close as possible to the access station in order to have a high signal strenth.

What software do I need in order to use the speed.io speed test?
speed.io does not require any special software. You need only a modern browser with Flash 9 installed. The newest version you can download here. Our test was successfully tested with many operation systems, MS Windows, Mac OSX and Linux.

Why do I get a message that I need Flash, where I already have it installed?
You need a newer version of Adobe Flash Player, at least version 9. The newest version you can download here.

Why the download / upload / connection / ping test does not work for me?
In most cases the reason for a not working test is a software which is installed on your computer, which manipulates the data between your browser and internet. Such software are often firewalls (or internet security suites) like e.g. Zonealarm, Kaspersky, Gdata etc. In the case one of our test is not working well at you, please try to deactive for the duration of the test this firewall. Please do not forget to switch them on again.

What are kbit/s and kbyte/s? Which one do you use?
When talking about internet speed two units are often used - kbyte/s kbit/s. You can remember 1 Kbyte = 8 Kbit. Internet access speed is usually measures in Kbit/s or Mbit/s, for example 16 Mbit/s. This is also the unit which is shown at speed.io. Internet browser as well as download-manager often use also kbyte/s, for example 2000 Kbyte/s (what corresponds to the speed which can be reached with a 16 Mbit/s broadband connection).

What kind of internet connections can be tested?
Basically all kind of internet connections can be tested in an accurate way with speed.io. Our system automatically recognizes your internet type and adapts our speed test individally. So that slowlier conections (e.g. GPRS or ISDN), but also very fast connections (e.g. ADSl2+ or VDSL / fiber internet with up to 50 Mbit/s) can be tested correctly.

How exactly do you test the download / upload speed?
Our download test measures the speed with which you can receive data from internet to your local computer. Our advanced technology downloads at the same time from 3 different servers and shows the achieved internet speed. We record up to 100 test-results per second and can therefore determine your speed very precisely.
Our upload test measures the speed with which you can send data to the internet from your local computer. It is especially important for video-conferences or when sending large e-mails. Our upload-test is adapting itself to your individual bandwith and sends several upload data packets to our worldwide server-cluster (distributed all over the world) in order to achieve the most accurate possible speed result.

What is the connection test and how do you measure it?
Our connection test is measuring how many connection your local computer can establish to the internet per minute. This results are determined by requesting a very small file from our worldwide server-cluster and analyzing the number of successful connections.
This test is especially interesting, because typical websites (e.g. blogs or news pages) nowadays consist out of very many small elements (like pictures or CSS styles). In order to show those websites fast on the screen, it is not only the download speed which is important, but also the response times as well as stability of the internet conneciton. All these factors are taken into account with this test type.

What is the ping test and how do you measure it?
Ping at speed.io is a little different that the classical ping (ICMP) in the command line. For our tests we use HTTP ping requests to our server-cluster. We are sending 10 HTTP-requests and show the achieved result. In most cases the result corresponds to the one with ICMP and is much more reliable when testing on computers with an activated firewall.

How does speed.io evaluate the test results?
Speed.io is evaluating how fast your internet connection is compared to how fast it "should be". That means, we compare the "is" to the "should be".
Example: if you have a 2 Mbit/s connection and achieve 1,9 Mbit/s in our speedtest, then it is "very good". If you have a 16 Mbit/s connection and achieve only 12 Mbit/s, then it is only "average", because you are almost 25% under the promised speed!
That means, that the evalutation does not say if you connection is fast or not, but rather if your speed reaches what your provider promised you.

My internet provider is not recognized correctly, what should I do?
We use the world-wide geo-database from MaxMind in order to determine your internet access provider. If the recognized provider is not correct, then it is possible that you are connected with a proxy or that the IP ranges changed recently. Here you can verify yourself which provider is determined by Maxmind.

Why is my internet connection so slowly?
There is a large number of factors which can influence (in a negative way) your internet speed. Most important are following:

  1. Performance of your computer (e.g. slow harddrive, low memory)
  2. Performance of your dsl modem (e.g. old firmware)
  3. How well your operation system is optimized
  4. Low signal strength when using wireless connection
  5. Other data connections at the same time when performing our test (VoIP calls, IPTV)
  6. Physical quality of your internet line (e.g. old cables)
  7. Temporary connectivity problems at your internet provider
  8. Temporary overload of our server-cluster. Thanks to our partner Akamai and Rapidshare we can almost completely ignore this factor. Our testfiles are distributed on over 60.000 servers worldwide with a direct connection to almost every access provider in the world. The system identifies automatically your provider and delivers the test-files from the nearest server with the lowest load.

How can I accelerate my internet connection?
There is no solution which can solve all the problems, because the reasons are very different. But if following following rules, you can be sure, that you perform the test absolutely correct:

  1. No other data connections may be performed at the same time with the speed test
  2. If you have a home network with other user, please make sure that they do not use the connection during the speed test
  3. Please close all programs and browser windows that could use internet and therefore influence the result (e.g. e-mail client, messenger, filesharing, etc.)
  4. If you use wireless internet, keep in mind, that the signal strength is very important for the achieved speed. So please place your laptop as close as possible to the access point so that you have an excellent signal. If you want very accurate test results, we recommend to use a cable connection
  5. If you use an old network card or a dsl modem with an old firmware (which support e.g. only 10 Mbit/s), you will be slowed when using a faster broadband connection (e.g. with 16 Mbit/s). Here we recommend an upgrade of the firmware or a purchase of a new decide
  6. Please switch off all kind of proxy servers if not necessarily reauired. All kind of services which are caching or manipulating the internet connection are influencing (in most cases in a negative way) your internet speed
  7. In some special cases your firewall or antivirus software can reduce yor internet speed. We recommend to switch them off during the speed.io test and do not forget to activate after

Very important: Please perform the test several times and at different daytime as well as weekdays.
If you followed all our advices and still experience a significantly lower speed that promised by your internet provider, then please contact their support department.
