Any idea why your download:upload ratio is so close to 1:1? Most people seem to have a 5-10:1 ratio. I don't know enough about the internet to understand why these numbers are what they are, but it seems that you are doing something different, or have some different equipment, that dramatically increases your upload speed.
The ADSL (Asymmetric Digital Subscriber Line) is a variant of the DSL (Digital Subscriber Line).
Technology allows download speed = speed of upload (DSL), but operators, castrate the upload speed to prevent network congestion using ADSL. Since it is studied to increase the speed of download not congested traffic in the same way that congests the increasing speed of upload. This is because if people have more upload speed can go up more material to the network and the effects on the increased traffic grow exponentially.
It is a decision of the operators. For flyers, the operator has chosen not castrate, surely its lines are ample and have had no problems. It is a better deal which can increase the number of customers in this case. How fortunate!
A little more explanation:
Traffic exchange programs (eMule, BitTorrent ..) is an increasing percentage of total traffic in data networks. Because of the increasing proportion of this traffic, operators, have not increased the upload speed because it is responsible for an increase in total traffic.
Roughly what happens is that P2P traffic is from users, all traffic received by a client should have been sent by another, so that altogether, the traffic that is attended by the network is limited by the upload speed of all broadband access.
A doubling of the download speed without changing the upload does not alter the amount of traffic that is attended by the network, while a doubling of upload speed without changing down, doubles the network traffic coursing and therefore the costs to the operator.
On the other hand, in a doubling of upload speed, download time is reduced more than half. In this graph you can see.
This is because the queuing time (before downloading a file) decreases non-linearly with respect to the load.
This is one of the main reasons for which the operators prefer to increase the download speed and not modify the rise.
