Here’s a typical output from iperf3 for the client:

iperf Done.

A few retries but I’m getting around 95 Mbits/sec on my (100 Mbit/sec) LAN.

This will give to an idea about the general performance of your LAN. If you start to send traffic to/from the NAS, you will probably see that your iperf3 numbers are reduced.

You should run iperf -c 192.168.192.60 assuming that 192.168.192.60 is the IP of your Win 10 machine

I just noticed something. It might only be a typo but iperf is not compatible with iperf3. You should run iperf3 on both machines.

Hi, im getting this now :
root@osmc:~# iperf -c 192.168.192.18

Should i change something in the client command ?

Better to use iperf3.

Hi, i found out the problem was my router. I connected the NAS directly to my laptop and the stream was very robust, at a constant framerate.

I called the provider to have it replaced.

I would like to thank all you guys in trying to pinpoint the errors i have been getting. It show that hardware is only worth as much as its support !!
