I'm assuming you didn't notice the mention in the purchase page. These agents have 100Mbps ports so with our app running on it, it would max out below 100Mbps.
The point of the speed test isn't really to see if you can max out the connection but to see if you have a usable amount of bandwidth.
For example, even with a 100Mbps max, if you were seeing 5 or 10Mbps for example, you would know there is something really wrong.
Hope this helps.
