ADSL Speed Test

What is throughput?

Throughput is the speed at which a network or computer transfers data at a particular point in time. It is an effective way of checking the optimum capacity and speed of a DSL connection. Throughput is measured in bits per second (bit/s). Assuming that it takes a bike, a car, and a bus the same amount of time to travel from point A to point B, the bus will be able to carry more data (passengers in this case) because it has a greater capacity.

In the same way, Throughput is the capacity of data that can be transferred within a particular amount of time such as 4MB or 14MB. DSL connections that promise better throughput have the capacity to offer larger volumes of data in a particular amount of time. Generally, DSL connections can transfer 30 megabits of information from one computer to another in one second and have a throughput of 30 Mb respectively.

However, Latency is as important in determining the speed of the DSL connection as throughput. Taking the afore-mentioned example further, it is of little benefit to the internet user if the bus takes an entire day to transfer data from A to B. The same way, Latency measures the time it takes to deliver data a prescribed amount of data from the serving entity to the client. The unit of latency is time.

How do I check my internet speed?

Checking the speed of your DSL connection is not rocket science. You can simply measure the speed by checking how long it takes to download files. If you have a 4MB connection then downloading a 7MB MP3 file shouldn’t take more than 14 seconds. In addition, a DSL connection generally takes 10 minutes to download a television show (350MB) and 20 minutes to download a movie (700MB).

For a more official assessment on your DSL connection speed, you can try one of the online speed tests. The internet is a wonderful resource for evaluating the download speed, upload speed, throughput and latency of your DSL connection. Online speed tests also provide other useful details about DSL connections such as the throughput and the latency. Here is what you need to keep in mind when trying the online speed test:

–  You should select the closest server location. For obvious reasons, a remote server will take more time to transfer data and will have a higher latency.

– You should download a sample file from the selected server. This process gives you a better idea of the upload/download speed of your DSL connection.
