• Yet another very slow boot topic.

    Hi, been using Antergos for about 2 years now, and finally decided to investigate this issue. The time until I get to use the desktop has been going up for some months now. Any help would be appreciated because I’ve read all the other topics and I still don’t know what to do.

    It was slow before, but it was much slower since I installed samba.

    man systemd.timer

    You might want to try changing how the timers start at files

    Under [Timer] you could add definition:


    Note that I haven’t tested this, but the manual page should tell you more.

  • also, updatedb is part of mlocate , mandb stil have if you do in terminal sudo mandb ,atleast to build up would it not be faster at boot later on.

    myself i dont have mlocate anymore :) but both are the longest in boot time as manual saids would be the thing indeed

  • @manuel Great, so now I know what man-db and updatedb are, and they were scheduled to run every 12h. That means that the second boot is much faster because those services don’t run the second time. I modified the files as you said, I believe to prevent the HDD from choking at boot, and lets hope the next first boot will be much faster.

    Is it possible to further improve boot time? This are the new logs that don’t run the named services:

  • @Morrison
    Based on the “blame” times I guess you have a HDD and not SSD drive? If so, then I’d recommend changing to SSD, that will boost your machine quite a lot, and not just the boot time.

    And often having more RAM (how much RAM do you have now?) helps if you are using “heavy” programs (but may not help much at boot).

  • @manuel OK, thank you.
