I currently have 1Gbit up/down connection and I'm having issues going past roughly half of that, I was downloading a game the other day at about 40 MB/s and Discord sounded metallic and Netflix was buffering all the time. Most downloads tops at that speed more or less but in speedtests I have about 930 up and down, but I noticed that, as soon as I turn on Qbitorrent, even if there's very little upload bandwidth usage (like 1 MB/s or so), the download speed takes a dip below 900. I checked CPU usage and it rarely goes beyond 30-35% even when I'm downloading big files.
This doesn't happen with the router the ISP provided, so I discard that there's something wrong in the fiber connection. This is my current config:

set allowed-interface-list=LANThere is a pppoe server because I connect the router the ISP provides to the Mikrotik to have a working phone at home, and that's how the ISP ONT works. The ipv6 nat rules are the default the router sets, there's probably a bit of security risks there but...
