    @KinderOvO moved your post to it's own thread for better visibility :)

    That config doesn't look like Centmin Mod's default format ?

    FYI, Centmin Mod is provided as is, it's up to you yourself to optimise and tune your server settings for your specific loads.

    Some hints on where to look for config/setting files for respective software below:

    Official site FAQ item 16 & 19 has some info at Centmin Mod FAQ - Menu based Nginx installer as does PHP-FPM page at PHP PHP-FPM - Centmin Mod - Menu based Nginx installer for CentOS servers and Centmin Mod Insights forum i.e. PHP Opcode and Memcached statistics pages | Centmin Mod Community

    As to specific values, optimisation is left to end user as I provide Centmin Mod as is.. forum search has some hints i.e. PHP-FPM - pm.max_children and the thread at PHP-FPM - WARNING: [pool www] server reached max_children setting (50), consider raising it | Centmin Mod Community for hints

    For MySQL, look at my mysqlmymonlite.sh addon which allows you to gather all relevant stats quickly Add Ons | Centmin Mod Community What you do with those stats are up to you i.e. provide it to hired consultants or post on forums (not necessarily this forum) in CODE tags for respective advice. I do not provide optimisation advice for free though, but other members are free to offer advice if they want.

    Also cpu load of 68 is cumulative over all cpu threads. So if you have a 32 cpu thread server, cpu load of 68 is really 68/32 = cpu load average of 2.125 or 212.5% which is high but can still be within normal depending on age and architecture of the cpu model/brand used.

    Indeed @KinderOvO is a premium member so has access to the auto installer too just need to contact me as per instructions at Wordpress - Wordpress Auto Installer + WP Super Cache Plugin [Premium Users] | Page 2 | Centmin Mod Community to get the auto installer install instructions etc ;)

    Yup! I became a member pro because centminmod and you guys already helped me a lot, and do not cost nothing to help as well.

    Already tested all configs, possible.
    - Nginx + fastcgi
    - Nginx + w3 total cache
    - Nginx + wp super cache
    - Nginx + hyper cache
    - Fpm (tcp) and (fpm sock)

    I can not reduce consumption.

    This and more powerful server data center, which would be another solution, rent 2 servers, it would be possible or would be slow.
    Obs: i use Online.net

    You only need this "Nginx + wp super cache"
    That's all.
    Even a 2GB Droplet on Linode can handle thousands of request per seconds with that.

    No I can understand! if I'm using nginx + wp-SuperCache
    the pages that visitors are accessing the who are cached, even with all the pages generated in cache, php-fpm and very high consumption.

    Because consumption is so high, it is using the cached page, I can not understand it.

    Nginx 1.13.x
    MariaDB 5.5
    48.78/32 threads = cpu load average of 1.524 which isn't that high ~152% cpu load. You need to follow suggestions of mine in 2nd post above to dig deeper into why

    Your site should be fine now, and should be more faster ;)

    After several hours of running, mostly 80% of the page are now cached.
    CPU load decrease a lot :)

    Hello! since migrated, come noticing a large drop of visits and page views, which can check the system, I think something is limiting the number of users, visitors, accesses.
    For every day I am less online users, confines itself as something my visitors.

    Only thing that can limit on the server level is CSF.
    You can stop CSF if you want.
    And also maybe cloudflare blocking some visitors.

    There can a lot of factors for the visits drop.
    If you still looking for help, ping me.
    I also moved a high traffic Wordpress site to Nginx (using CentminMod for easy setup) and you will be surprised the results I got :)
