Today, after upgrade to Debian Stretch i was looking startup loaded services and system boot-up performances through systemd-analyze* command.
Looking results , excluding kernel time, system took 1 minute and 42 second for the boot.
OK , i don’t have an SSD and there are a lot of services like tor, virtualbox , Plasma etc.
Anyway it deserve a more detailed check, so i executed systemd-analyze blame* for understand if there is a particular slow service or if there are just so many
As you can see , outcome show that racoon.service takes 32 secs to start.. this service (ipsec) for my needs it is useless. Therefore i typed (with sudo, or being root) Systemctl disable racoon.service
Afterthat, i restarted system and i typed again command System-analyze to see results:
Nice, we cut 17 seconds 🙂
In general, making a check to verify and identify which services taking time (and especially if are necessary for our needs) it is something that ,as in this case, is really useful 🙂
*Despite my screenshots, you can systemd-analyze and systemd-analyze blame whitout root privileges.
