Session\ConnectionSpeed (aka connection_speed in libtorrent) is ignored

[reardonia]

qBittorrent & operating system versions

on Linux, using qbittorrent-nox (headless) v5.0.3

What is the problem?

the outgoing connection throttle is completely ignored. Setting to "0" or "1" or "100" doesn't matter, qbt just seems to do whatever it wants (averaging >>100/connections per second)

Steps to reproduce

No response
