Figured this out myself with trial and error. Here is a guide how to use iperf to test networking performance between your QNAP and your client devices, in my case, Desktop win10 PC.
pre-requisite
- In app center, setup my qnapclub as a repository. there is a guide for that here
https://qnapclub.eu/en
- install iperf from the qnapclub repository via app center
- download iperf for your windows here
https://iperf.fr/iperf-download.php
- extract the iperf windows contents to this location e.g.Code: Select all
C:\iperf-3.1.3-win64\iperf3.exe
now go to windows start, type cmd, right click it, open as administrator
then type
Code: Select all
cd C:\\
Code: Select all
cd C:\iperf-3.1.3-win64\
then
Code: Select all
iperf3 -c "your QNAP ip address without the quotes"
Code: Select all
iperf3 -c 192.168.0.210
This is my result testing speed between Desktop pc and TS-877 over my local network
Code: Select all
908 Mbps = 113.5 MB/s
And when you are done testing, you can go app center and disable iperf, until you actually need to use it
process should be roughly the same on smartphone e.g. android/iphone...
i wanted to try it by testing from 1 qnap to another using winscp/putty, but i couldn't get that to work. there is an old guide here though that may help

The location for iperf on my qnap was
Code: Select all
/share/CACHEDEV1_DATA/.qpkg/iPerf3/bin/iperf3.exe
