    Hello :)

    I am wondering why not have Nginx auto worker_processes set to Auto as default on Centminmod?

    Don't see any problem with this and it will auto scale....

    Or is it better to set a value there than auto?

    Thanks :)

    Not all of us prefer to give all the CPU to Nginx worker.
    Since we all have Mysql and PHP running on the same server, it's better to divide the total CPU for each Services.
    I always give Total CPU / 2 to Nginx, Total CPU x 2 to PHP via dynamic.

    But it should get more cores only when needed :)

    Ok anyway it's not an issue just a thought that may be better to use that option :)

    Setting auto uses all cpu detected threads always it doesn't use more cores when needed. On a LEMP stack with MariaDB MySQL and PHP-FPM servers as well, you want to leave some of the cpu threads/cores to other services/servers running. If you have Nginx only web server i.e. reverse proxy caching front end or load balancer using Nginx running only Nginx, then auto might make more sense.
