The maximum download speed is dependent on your Network bandwidth. Supposing your maximum bandwidth is 8 megabits/sec. For this bandwidth you shall get a maximum of one eighth of 8 megabits in megabytes/sec or i megabyte/sec speed. In kilobytes it shall be one thousandth of this speed per second or 1000 kilobytes per second.
Due to transmission losses, hysteresis etc. if you get 90% efficiency then your maximum speed shall be limited to 900 kilobytes per second. And no matter which download manager you use it shall never be more than that. Windows 7 Network is capable of working with the maximum speeds. Therefore a download manager is like a placebo that gives you a feeling of security.
It is of real use only because of its ability to resume broken downloads.
As Opera Browser can do that equally well, why have a needless program installed. And with today's stable bandwidths, download managers have become more and more irrelevant.
