I Have disabled cups-browsed.service with this command:

sudo systemctl disable --now cups-browsed.service

And for my surprise, after that, now i can feel less input/video lag

For my surprise ...

Anyone else can test, so we can really sure it is not placebo?

Disabling this service should not affect input/output lag, as cups-browsed is a service that enables network printing and should not have a direct connection to input/output lag.

  • I tried adding lp user to group input, because printer needs sometimes usb connection ... is it relevant to avoid lookup? Commented Feb 26, 2023 at 21:46
  • Not really, it's too little load to be noticeable. Maybe there is a loop in the network? Then there is a chance that it can significantly reduce network bandwidth. You can always ping the website (for a few minutes) and start printing something, if the response time varies greatly, then you can start looking around the web for the problem.
