gnome-system-monitor show incorrect network speed

[vodopad27]

Hello, i have Ubuntu 19.04 and internet with 100 megabit per second (max 12.5 megabyte per second).

I copied file via scp over vpn from remote server to my desktop:
vodka@vodka-PC:~$ scp -o 'ProxyJump=secret_user@192.168.228.11' secret_user@192.168.224.196:/tmp/28/secret_database_2019-08-27.dump /tmp/

You can see in screen (https://i.imgur.com/OfH3GWF.png) that download speed was 9.1 megabytes per second (72.8 megabit per second), but in system-monitor we saw 187.3 megabits per second, which not unachievable with my network...
