Download speed depends on the speed of both your and the other computer's Internet connection. For Web pages, it also depends on how they are written. Web programmers can use various techniques to make their pages download faster.
DTR refers to the speed of transfer between any two devices; for example, a computer and a printer, or a CD-ROM drive and a hard drive. It depends on the technical characteristics of the devices and the way they are connected.
Download rates are measured in megabits per second (Mbps) for broadband connections, or kilobits per second (Kbps) for dial-up, modem connections. Transfer rates are measured in bits per second (bps), or for devices such as DVD-drives in gigabytes per second (GB/sec).
Advertised speeds are rarely, if ever, possible to achieve. For downloading, they vary hugely depending on how far you live from your service provider and other factors. For transfer rates, especially those involving hard disks, they depend on how big a file is and where it is on the disk.
Speaking as someone that has had Hughesnet for over 11 years .....
Speeds on many beams and Gateways may not reach "maximum" advertised speeds.
Keep in mind that those speeds are "up to" maximum speeds under ideal conditions.
Even during the late night hours many users will be using a download manager to get larger file downloads with their computers unattended.
It looks like each Gateway facility is tasked with the traffic from 4 beams and those four will not necessarily be geographically adjacently located.
Also at this time Microsoft is spewing out Windows 10, not only to those users that have "reserved" it but also to users of Win7/8/8.1
In the aggregate that is a lot of traffic on a "shared resource".
Here is map I have been assembling (work in process) that will show just how widely scattered beam location to gateway is.
You simply can't expect to have max advertised speeds very often ... that is the reality ......
