Pay attention on Cpu% "sy" in top, it shouldn't be high. New kernel -- new drivers. You may have hardware compatibility problems (or interrupt storm). Also, check your drive health with smartmontools (bad drive may cause bad performance): https://packages.debian.org/buster/smartmontools You can also measure its performance with fio https://packages.debian.org/buster/fio
