Screenshot of files being moved and monitor's display

Description of problem:
Running the monitor app on a gigabit Ethernet connection gives ridiculous statistics on the rate of transfer.

Version-Release number of selected component (if applicable):
gnome-system-monitor-3.24.0-1.fc26.x86_64

How reproducible:
I'm running Monitor on a box that is being used as the source of a 650GB transfer of thousands of files via rsync to a backup server. Monitor's statistics and graph are orders of magnitude understated. 

The screen snapshot should be referenced. What it shows is the Monitor screen overlayed upon an lsof output of the files currently in process. These files are almost all in the 1GB range as they are video (movie) files. The following lsof is used: 
   lsof -p 8804 -r |grep billlaptop
and this command refreshes the display (-r) every 15 seconds. As can be seen, these large files are being processed and yet the monitor screen shows some piddling throughput statistics.

Steps to Reproduce:
1.

3.
