Strapi documentation doesn't talk about good practices of running Strapi in cluster mode, that is one of the cases to optimize and take advantage of your server, where you can use the pm2, like the docs already mention.
Could one of you create a section to talk about cluster mode best practices in the documentation please?
I don't know if it's relevant, but in my tests, I already have some errors like "sorry, too many clients already" when running more than 9 instances in cluster mode.
