speedtest slow while iperf result show faster

[niaosuan]

Speedtest hosted with apache2 is showing slower speed than my iperf result, It is directly browse to the server.

• HTTP only
• apache2, PHP 7.4.33, OpenSSL 1.1.1n
• Server hosted in LXC proxmox VM
• Debian 11
• Mozilla firefox 109.0.1, Chrome108
• Librespeed without extra configuration

#Result:

Any advise?

Is the test carried out by HTTPS address or by HTTP ?

Similar issue happens to me while I attempted to run tests from an android tv box and a very old computer (pentium cpu, BIOS dated 2012). I guess the processors of client devices made impacts on the results, they are not capable of browser and javascript jobs…
