Network utilization data (DataReceived/sec, DataSent/sec) using “wmic” differs from Task Manager information

Issue

This Content is from SuperUser. Question asked by Otis Lin

I want to get BytesReceivedPersec and BytesSentPersec from command.

I used this commnad.

wmic path Win32_PerfRawData_Tcpip_NetworkInterface get Name,BytesReceivedPersec,BytesSentPersec

And I got this response.

BytesReceivedPersec  BytesSentPersec  Name
0                    0                Intel[R] Ethernet Controller [3] I225-V
1397496619           51305183         Intel[R] Wi-Fi 6 AX201 160MHz

I saw this result will increase over time, So i try to keep the last value, and using (current – last)/1024 to Kbps.

result like this
in: "4.84473" , out: "1.67578"

But in the Task Manager like

enter image description here

Why the result has very big different?
