Insight continues to offer the 20 mpm speed for the $20.00 increase in cost, and I know it works but I am puzzled as to how. Upload speeds are so much slower, even with a T-1 or another higher speed that a company may offer, how does the end user reap the benefit of the double speed when there are these caps on what a server can send?
A T1 (also called DS1) connection isn't really that fast -- only about 1.5 Mb/s. What you're really paying for with a T1 is a guaranteed symmetric connection at that speed and guaranteed uptime.
The Big Boys have Internet backbone connections that can move traffic at tens or even hundreds of Gb/s. (How fast can Google move data onto the Internet?)
Is there a limit where the upload speeds could not keep up with the download, 40 or 50 mpm? I know there must be a simple answer.
I'm not sure what you're asking here. There is a limit to your download speed that's caused by the asymmetric connection speed. Downloads are sent in packets and each packet has to be acknowledged. If your upload can't acknowledge the packets as they are arriving because it's so much slower, then you've hit a limitation that can only be fixed by raising the packet size. This is one of the big problems with telephone modems, but probably doesn't happen that often with cable.
