> Or  12,800.00 KByte (The multiplying factor for network data is 1024
instead

> Theoretical maximum             12,800.00 KB/sec         43.9 GB/Hour
> Practical reality                        10,000.00 KB/sec        34.3
> GB/Hour
> in our example                  34,935.96 KB/sec        119.9 GB/Hour

> As you can see, the  values greatly exceed the theoretical maximum.
