`systemd-analyze - Analyze system boot-up performance`_:

Prints a list of all running units, ordered by the time they took to initialize.
This information may be used to optimize boot-up times.

.. note:: The output might be misleading as the initialization of one service
          might be slow simply because it waits for the initialization of
          another service to complete.
