Public bug reported:
Gnome System Monitor on Ubuntu 24.04 shows completely wrong network
(Receiving) transfer speed and Total Received values.
Hardware: Framework Laptop 13 _AMD Ryzen 7040Series
- Laptop is connected via ethernet (framework network expansion card) to a 1
Gbps switch
- copying around 200 GiB of (large) files from an Ubuntu Studio 22.04 machine,
also connected via ethernet.
- transfer is over sshfs
- using mc to do the copying
- mc shows transfer speeds of ~100MiB/s, which is to be expected on a 1 Gbps
LAN connection.
- Gnome System Monitor, however, consistently shows ~ 200 MiB/s on the
Receiving side (which is impossible since 1 Gbps maxes out at ~ 125 MiB/s in
ideal circumstances)
- No other network traffic-intensive processes or apps were running during the
copying of the files
- When the copying was done, 'Receiving' went back to ~ 1 KiB/s
- The 'Total Received' value had risen well over 400 GiB (while only 200 GiB
was actually transferred)
So it seems Gnome System Monitor *doubles* all the numbers, at least
when it comes to reading from the network.
If any more details are required, I'd be happy to provide them.
