If you’re using Internet services such as Unifi or Streamyx, you can check your speed, using their own speedtest tools. Alternatively, you can use the extremely useful tools available online, speedtest.net.
However, if you’re running a website and you wanted to know your bandwidth usage, that’s a different story. Depending on what OS you’re using, either Windows or Linux, there’s few good tools. We will cover that later.
Remember, bandwidth speedtest for communication services and bandwidth meter for webhosting is totally a different things.
