Your system generally isn't the fastest, so there aren't many obvious gaps, except this blatant one:
bře 18 17:57:26 P-IV ntpd[1174]: Listening on routing socket on fd #22 for interface updates
bře 18 17:58:00 P-IV systemd-journal[268]: Forwarding to syslog missed 50 messages.
bře 18 17:58:47 P-IV ovpn-client[1100]: ERROR: could not read Auth username from stdin
bře 18 17:58:47 P-IV ovpn-client[1100]: Exiting due to fatal error
bře 18 17:58:47 P-IV openvpn[1060]: Timed out
So the timed out openvpn delays the boot by about 1.5 minutes. Do you regularly enter your OpenVPN password at boot under upstart? Can you temporarily disable openvpn and check if boot time is comparable to upstart?
