    I recently installed it on a brand new dedicated server i got with following specs:

    32GB Ram
    Intel Xeon E3 1245v2 (4C/8T)

    However, i noticed that nginx.conf only uses 1 worker process. Would I need to optimize those settings my self, if yes. What ones would I need to change?

    I assume zend op cache, nginx.conf and not sure about others. If I remember right, other VPS I've installed this one gets 2 worker process or more.

    nginx.conf should of been auto optimised for worker processes out of the box via inc/cpucount.inc function - so you can see what functions and formulas are used there

    basically for 7 or 8 cpu threads formula is
    Code:
    if [[ "$NOCPUS" = "8" || "$NOCPUS" = "7" ]]; then
        NOCPUS=$(echo "$NOCPUS"/2.333 | bc)

        echo
    if [[ ! -z "$WORKERCHECKA" ]]; then
        #echo "set cpu worker_processes to $NOCPUS"
        sed -i "s/worker_processes  1;/worker_processes $NOCPUS;/g" $NGINXCONFCPU
    elif [[ ! -z "$WORKERCHECKB" ]]; then
        #echo "set cpu worker_processes to $NOCPUS"
        sed -i "s/worker_processes 1;/worker_processes $NOCPUS;/g" $NGINXCONFCPU
    fi
fi
    so 7/2.333 or 8/2.333 rounded to nearest integer for worker processes

    it's only auto part, rest of your configs outlined at Centmin Mod Configuration Files - CentminMod.com LEMP Nginx web stack for CentOS is left to end user optimisation

    Centmin Mod is provide as is, so short of scripted related bugs or issues, any further optimisation to the web stack components - nginx, php-fpm, mariadb mysql, csf firewall etc or web app specific configurations are left to the Centmin Mod user to deal with. So I do not provide any free support for such.

    However, Centmin Mod users are free to help each other out and ask questions or give answers on this community forum. My hopes are that this community forum evolves so that more veteran long time Centmin Mod users help new Centmin Mod users out :)

    To help with optimisations, there are various tools and commands you will want to read up on and learn for basic system admin tasks and troubleshooting.

    Sorry for bumping this thread, but when I install centmin on UpCloud few days ago, worker processes is set to 1, I have to change to 4 because I have 4.

    Yep, maybe 2 was set, but if I have 4 worker process

    Code:
    # grep processor /proc/cpuinfo | wc -l
4
    then should be 4 not 2 in nginx.conf?
    Code:
    # cat /usr/local/nginx/conf/nginx.conf
user              nginx nginx;
worker_processes 4;
worker_priority -10;

worker_rlimit_nofile 260000;
timer_resolution 100ms;

    depends on your usage patterns but if you have mysql and php-fpm and redis/memcached best to not hog all the cpu threads

    You can try and see if PHP isn't too loaded.
