No… 19.3MiB/s = 20.24 MB/s = 161.9Mbps
the speed test (speedtest.nl) usualy indicate the speed in Mbps (megabits per second).
then a speed of 75Mbps (on speedtest.nl) correspond to : 9.4MB/s or 8.94MiB/s
did you check the refresh rate of the tab in ksysguard? put to a lowe refresh rate (0.5s) and check the numerical value in the legend…
exemple on mine:
speedtest give me a result of 520Mbps.
then 520Mbps = 62MiB/s = 65MB/s (1Gbps connection to the /modem-router with 1Gbps switch between)
on ksysguard I have this (burst… the graph is not accurate… the digital value displayed is 0 or or around 130Mib/s during the test) if you look the average it’s about 60MiB/s (don’t forget you have a router/modem between)
on the network applet I have this (all correct)
I tried to add again the desktop widget but it did not wanted to display anything and I don’t know why…
I had the same symptom as you… factor 2 on desktop widget… but this factor is what I see in ksysguard… so it seems related to that… and I would not relay on the desktop widget…
