Hi Robert,
Thanks for reminding me of systemd-analyze. Completely forgot about that.
Here is the output of the command
=====================================================================
62389ms networking.service
2819ms bootlogs.service
2533ms loadcpufreq.service
2402ms ssh.service
2271ms xrdp.service
2203ms cron.service
2059ms console-kit-daemon.service
1236ms avahi-daemon.service
1205ms connman.service
1181ms wpa_supplicant.service
1120ms systemd-logind.service
1086ms connman-vpn.service
1027ms boot_scripts.service
961ms rc.local.service
958ms capemgr.service

240ms hdparm.service
231ms run-lock.mount
230ms systemd-tmpfiles-setup.service
219ms run-user.mount
193ms pppd-dns.service
128ms systemd-remount-api-vfs.service
113ms boot-uboot.mount
66ms remount-rootfs.service
48ms console-setup.service
38ms sys-fs-fuse-connections.mount
37ms keyboard-setup.service
==========================================================================
So it looks like networking.service is eating up all the time. Is it safe
to disable this service with connman installed?
