How do i analyze systemd boot-up performance?

systemd-analyze time prints the time spent in the kernel before userspace has been reached, the time spent in the initial RAM disk (initrd) before normal system userspace has been reached, and the time normal system userspace took to initialize. Note that these measurements simply measure the time passed up to the point where all system services have been spawned, but not necessarily until they fully finished initialization or the disk is idle.
$ systemd-analyze Startup finished in 1.175s (kernel) + 2.958s (initrd) + 3.643s (userspace) = 7.778s
