Consider that with the latest hardware your processor is under 1% or 2% load running a bloat machine like windows even if you used the lightest weight distro without any desktop environment at all the maximum possible performance gain would be 1% or 2%.
Finally starting my self hosted journey. I have everything I need I’m setting up a 6tb nas for linux iso’s photos and files. And I recently got a “broken” laptop that works perfectly fine that I will use for running all my applications in proxmox such as immich, jellyfin and nextcloud. And probably many others in the near future.
