Not sure what I might be doing wrong but hAP ax2 UDP Upload test is low when testing from Router speedtest tool (Console) to Btest/server on PC.
Doesn’t seem to matter if it’s wired or wireless.

Can you perform a test with two machines, using i.e. iperf?
It would seem so.
I'm getting some strange results, So I'm testing from a PC to pi4 8GB. I'm going to spin up another server later to test again.
If I use multiple streams Linux to Linux? WSL I'm loosing as you can see below But.... If I test again from pi4 to PC iperf3.exe using
UDP single stream 100M if works fine! second set of tests.
pi4 has iperf3 version 3.6 (something-something fixed in version 3.10 UDP Multi) hence i want to spin up another server.
PC has WSL Ubuntu - Hyper-V shared connection iperf3 version 3.13
I need a better match to make sure what I'm seing isn't an iperf -v mismatch problem.

If I do the same test single stream Linux to iperf3.exe I get this..

i'm not sure Windows iperf3 does -P properly at all.
I'll pop back when I've got more clean results
@erlinden
Test to a proper linux server (iperf3 v 3.9) gives me no such nonsense.
So that would be a no it doesn’t do the same thing.

So I’m out of Ideas.
That’s why it was suggested to use iperf on both sides passing over that Tik router.
My go to tool for such cases is always iperf3 in container or bare metal (and HE.NET app on Android if needed).
I wasn’t aware that it didn’t work properly Windows btest.exe.
erm.. how about x86 Mikrotik in a VM would that work properly ?
Depends on the CPU you have on that VM and the available network card.
There is a public Btest server available hosted by our own North Idaho Tom Jones, if you want.
I believe it can digest up to several Gbps 
http://forum.mikrotik.com/t/public-mikrotik-bandwidth-test-server-s-now-shutdown-as-of-april-1st-2025/94863/1
If only I had that much bandwidth 
27 Mbps… meh
Ok so installed Hyper-V then CHR on Windows11 yup Windows11 it works now I guess.

But guess what, it’s the same as btest.exe oh well more useless info gained so someone else doesn’t need to.
It works very well guys, big thumbs up
