Tyrro i really appreciate your help on this, i need to dig deeper into this stuff and learn how to do a proper setup.
I'm using easy engine defaults, and i've already changed the values. So far so good.
I've also reduced the php7-fpm max children to a more reasonable value, it was at 100.
By the way, i'm also using Cloudflare as CDN. This website is something for 500-1000 online max!
Disabling the other database services is a simple thing to do?
If i comment the settings on mysql will it be disabled?
Thank you once again, i really like managing my servers but i'm still a noob.
