Slow upload speed, i need advice!

@Schmu

Is there another netdata graph suspicious during upload, which could narrow down the real bottleneck?

No, everything seems to normal.

@Schmu

Just a stupid thought (but at this point maybe better than no thought): could the web server be bound to another network interface, which doesn’t provide the higher up-/ download speeds (wifi)?

No

@Schmu

Did you configure any routes which are not optimal? Maybe run a tracert / traceroute to see the used route and rule out that there are slow network paths?

Like i said, any other type file transfer is perfectly fast. Even if i download file from usual directory with http. Server is 6 hops away always. Every hop is 6ms-15ms.

@Schmu

And your device you are testing the download/ upload rates with is definitely not using wifi for that, right?

Yep, no wifi involved here

@tflidd

Did you just try to download a large static file with your webserver?

Yup, fast as it can be

Only problem is uploading to nextcloud, no matter if using web browser or nextcloud client. ~10mbit/sec

                              EDIT: Finally found a solution!!!

Disable http2 on nginx

Getting now ~500mbit/sec upload to nextcloud server. Huhh, unreal. Spent like forever finding whats wrong with this server.
But why nginx http2 making upload slower? I have not seen on other places where i use nginx.
