Maximum throughput is dependent on the sample time - if you change from 1 second to 0.1s to 0.01s you will notice higher and higher peaks.
A 1Gbps ethernet pipe is clocked at 1000000000 bits per second so that is the maximum rate bits will go. But because of the overhead from headers and encapsulation, enforced gaps between packets, the actual thorughput (and data goodput) will be different.
The IO graph is based (I think) simply on the sum of frame lengths in the sample period you have chosen.
