Connection speed measurement is a technique to assess the quality of your internet connection. This test measures the bandwidth of your ISP and latency that is causing the difference in the speed. Before we review some of the best online connection speed tests, you need to have a little know-how about these two terms: Bandwidth and Latency.
Bandwidth
In computer networking, it refers to the data rate that is supported by the network connection or the interface used. It is often measured in terms of bits per second (bps). Bandwidth actually represents the capacity of the internet connection that you’re using. The greater the capacity of the connection, the greater speed you’ll get from it. For example, if your ISP says that you have a connection of 3.1Mbps (WiMax or ADSL), it means that you’ll get 3.1Mbps (Mega bits per second) or 300KBps (Kilo Bytes per second) speed, at least theoretically. The old V.90 modem only supported bandwidth upto 56Kbps and modern ADSL modems support upto 100Mbps speed.
Latency
It refers to the delays that occur during the network data process. Lower the latency, higher the quality of the connection, whereas, higher latency connections suffer longer delays and decrease in their speed (bandwidth). So if your ISP promised you the speed of 3.1Mbps and you’re not getting the same speed, latency might be a cause of it as it creates a bottleneck that prevents the flow of network data. Faulty phone lines or lower signal strength are some of the reasons for latency. Latency is measured in terms of milliseconds (ms). Ideal latency rate in a DSL connection is 100 millisecond. One way to find out latency of your network is the ping command.
(Before starting any network speed test, make sure that you’re not browsing any other website or downloading anything as it may effect the overall results of the test).
Speed Test
It is one of the most used online speed test websites. You can choose from the several available internet providers and can also choose the closest server to you. SpeedTest.net uploads a 1MB file to a server and in the process measures the bandwidth of your ISP. For latency check, they have a sister site called Pingtest.net.
With a cool flash interface, it’s real fun to measure the bandwidth and latency of your internet connection and at the end you can also compare your results with other ISPs or different servers. Speakeasy.net was also made by the people of SpeedTest.net
Broadband Speed Checker
It’s a UK based website that gives you the option to check for the download and upload speed only. You can also see your previous results and share results with other people.
Oz Broadband Speed Test
This one is a little bit different as it provides you the option to run a test of your own choice. On the main page, you’ll get the options of different file sizes to choose from.
It ranges from a dial up 70KB to an ADSL2+ 15MB file. The reason for different tests is that the larger the bandwidth you have, only a larger file can truly test the speed of its connection. On an ADSL2+, 50Mbps connection, a mere 1MB file won’t show the accurate results.
Upon choosing a test, a pop up window will open and the test will start. The results will be shown after the completion. You can also compare different broadband connection results with different filters like peak or off peak data, speed and price.
Broadband DSL Reports
This website provides different kinds of online speed tests not only for a PC but also for different mobile platforms, with latency support. There are two kinds of testing platforms, flash and Java based. Java platform provides more accuracy and like all other tests, flash based program may not show accurate results if you have slower computer. You can compare results and filter or get data of your ISP.
CNet Speed Test
Last but not least, one of the oldest online speed test. With only a fixed server in the US. This will download a file of 1MB when you’ll choose your type of connection from the list.
