I apologize for the out of topic question, but since systemd-analyze incorporate the firmware boot time I wonder if you may have any trick to share in order to improve it.
Here is my boot timing (using systemd-boot and a lz4 compressed initrd): $ systemd-analyzed Startup finished in 14.156s (firmware) + 1.098s (loader) + 7.473s (kernel) + 2.608s (initrd) + 1.766s (userspace) = 27.103s I have a few questions on how to improve things: - obviously for the firmware time there is not much to do except maybe try to turn off some uefi autodiscovery settings - the loader is perfect, I have configured it with 1s delay for the menu - I am surprised by the kernel time. What does it include? - the initrd time is fast but I am surprised too that it is slower than userspace [but I guess it is because of the mounting of / which also mounts /home as a subvolume]. The initrd is also handled by systemd, so the switch root is done by initrd-switch-root.service which calls /usr/bin/systemctl --no-block --force switch-root /sysroot I don't know how much information is transmitted during this switch, is there a 'systemd-analyze blame' I could do to see the time spent in the initrd (without using bootchart)?
