systemd-journald slows down boot process

[Clemens Eisserer]

Hello,

I recently tried to improve the boot time of a low-end laptop (normal
hdd, no SSD) running Fedora23 (+lightdm + xfce), and disabled unneeded
services which were loaded at boot.
However the systemd-journald.service still takes a lot of time to get
started (11.2s), dispite reducing the maximum log size used by systemd
to 64m (found the suggestion in several forums).

Curently, the critical chain looks like:

[root@localhost elfie]# systemd-analyze critical-chain

graphical.target @20.328s
└─multi-user.target @20.327s
  └─NetworkManager.service @18.317s +1.995s
    └─dbus.service @16.256s
      └─basic.target @16.209s
        └─sockets.target @16.207s
          └─iscsiuio.socket @16.206s
            └─sysinit.target @16.139s
              └─systemd-update-utmp.service @16.084s +53ms
                └─auditd.service @15.613s +459ms
                  └─systemd-tmpfiles-setup.service @15.152s +429ms
                    └─systemd-journal-flush.service @14.511s +621ms
                      └─systemd-journald.service @3.268s +11.222s
                        └─systemd-journald-audit.socket
                          └─-.slice

Are there any tools available for analyzing this any further?

Thank you in advance, Clemens
