We sell downloadable full HD films from the site but customers complain about download speed that averages 300Kbps. Our server provider said it's an "OK" speed and offered a dedicated service. He let me test the speed from one of the sites sitting on such a server and the download was about 700kbps.
The problem is, I need at least 2Mb/s speeds as the file sizes are huge and I want the clients to be satisfied. I was wondering it it helps to host on 2 or 3 servers to solve the problem. Any ideas?
