debian - boot time between different kernels
by milomak from LinuxQuestions.org on (#52MRV)
i'm having a distinct difference in boot times between 2 kernels on my debian sid install
So this is the gold standard at the moment (5.2.0-21.2-liquorix-amd64)
Code:mac ~ # systemd-analyze
Startup finished in 38.197s (kernel) + 18.085s (userspace) = 56.283s
