Is ubuntu not based on debian repos anymore? I remember when it was a debian unstable/latest(?) plus the “Ubuntu” part itself. Debian was a set of versions, from stable to “probably will break”, not a single “old” distro. Anyway it always feels strange when someone claims X is slower/faster than Y, where X and Y are both ~the same kernel and the base system. As if debian maintainers didn’t know some secret “non_vanilla_run_faster: true” settings for the same kernel that was 30 years in development already. Most distros are just slightly different gui programs running on top of basically the same gnu/linux binaries.
