10 times more bandwidth is not 10 times faster
Complaints from the users about poor response time or an altogether missing connection to the internet, often results in the it-department investing for more bandwidth. But how much do we need, and from which parameters should we choose our new bandwidth?
Internet connections are not “just” internet connections, so what can we expect from a new connection with increased bandwidth?
We will take a look at an example where we upgrade from a 10 Mbit/s fiber to a 100 Mbit/s fiber anticipating that when we increase the internet bandwidth tenfold, then we also increase the user’s speed tenfold.
But before we continue with the example, it is important that we take a look at the properties of an internet connection and which impact these different properties have on the internet connection.
Property 1: Bandwidth [bit/s]
In daily speech, the bandwidth is what we associate to the speed of the internet connection, and that is typically also what we buy when we choose an internet connection. Bandwidth is typically presented in bit/s, kbit/s, Mbit/s or Gbit/s.
Depending on our need for upload and download on the internet, we can choose a symmetrical or an a-symmetrical connection. A symmetrical connection is a connection where there is the same amount of bandwidth for download and upload (e.g. 10+10 Mbit/s), on an a-symmetrical connection there is more bandwidth for download than upload (e.g. 2 Mbit/s download + 512 kbit/s upload).
