First, see the screenshot.
In both places the speed is indicated in kB/s. If I set 80,000 kB/s why does it swing at a speed of 2.3 kB/s and not 12800 kB/s?
Secondly, 100 Mbps is 12800 kB/s, which is already within my scope. Since 80000 kB/s is more than 12800 kB/s.
Thirdly, if I put a value of 1,000,000,000 kB/s there, the speed will be just as slow.
