If I had not seen it with my own eyes, I would never have believed that disabling the LCD had any effect. But it did!
With disabled LCD I got ~500Mbit at my first speedtest. Unfortunately it looks like this was a one-time shot. I was not able to reproduce it (even with some JDownloader download tests).
But anyhow I do get more then before. Around ~400 - 450MBit. Maybe there is still something to “tune”.
I also
Here is my whole config for reference. I’ve deleted my firewall adress lists (because the firewall was deleted / disabled at this point (I left only the fasttrack rules in place because without them speed dropped to 140MBit)), dhcp-leases and obfuscated my domain-things for privacy reasons.
