Manual Speed Testing

This test is very straightforward and gives a good representation of how your connection is performing by using data files on the Virgin Media network.

We keep a lot of really large data files on our Downloadable Games Demos page. Try downloading four files from here at the same time (choose large ones, above 400MB in size) and let the connection to settle for 30 seconds or so. Depending on which browser you’re using, you’ll be able to add up the speed of each transfer and get a total figure, and that figure will give you an indication of how fast you were downloading.

In Internet Explorer, you’ll see the figure as KB/Sec or MB/Sec – that’s Kilobytes or Megabytes per second. To convert to kilobits, multiply by 8 and allow 10% extra for general communication.

For example, in the image below, the rates shown add up to 5.62MB per second.

Here’s how to turn this into Mb/sec (megabits per second) and find out your speed:

  • Multiply 5.62 by 8 – this gives you almost 45 megabits per second.
  • Windows Download Manager only shows you data related to the files being transferred. On top of this, there’s other data flowing, which supports the background communication that lets you use the internet. To allow for this extra hidden data, add 10% to the figure you’ve got so far.
  • So, in this example we get 45Mbps + 10% = 49.5Mbps.

I’m still not getting the result I hoped for
