speedtest behind nginx upload numbers wrong? about speedtest HOT 4 OPEN

I am getting correct numbers without the patch, so for me there is no need to change anything. I think it is important to disable any buffer/caching in your nginx config.
This is my nginx config:

location / {
       proxy_http_version 1.1;
       proxy_set_header Upgrade $http_upgrade;
       proxy_set_header Connection "upgrade";
       proxy_set_header Host $http_host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header X-Forwarded-Host $http_host;
       proxy_set_header X-Forwarded-Server $http_host;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto $scheme;
       gzip off;
       proxy_redirect off;
       proxy_buffering off;
       client_max_body_size 256M;
       proxy_pass http://localhost:8181/;
    }

Hi @santowiryamann

I'm sadly aware the speedtest is not running as expected behind a proxy.
This is something I would be able to fix, but to be honest, which is not in top of my list.

I definitely reckon it as a bug, and will try to investigate at some point.

Regards.

I found an irregularity in the bandwidth test part.
I tagged a version 0.5.4-alpha.0 that you may try.
I'm not sure that it was the root coause, but let me know if it helps.

Also built and available through Docker: https://hub.docker.com/layers/e7db/speedtest/v0.5.4-alpha.0/images/sha256-35ccac2eca91e63f46e706d9630353dfa0e498f1abc6e3b8c9b52cf5ad73ab74?context=repo

I'm using speedtest with docker, behind Traefik proxy (also docker, same docker host). As I was having similar issues, I decided to test out the 4 combinations

Master + Traefik = 2000+- Mbps
Tag + Traefik = 1200+- Mbps

Master + direct = 360 Mbps
Tag + direct = 223 Mbps

Running iperf3 between client machine and docker host I got 375Mbps.

So I guess that the master is giving out correct numbers if the proxy is not messing up the values.

I can't look deeper now but besides knowing the specific settings for the proxy (as mentioned by @maltechx), maybe the test can be updated to generate unbufferable/compressible random text? As not everyone will be able/allowed to change their reverse proxy settings
