How to remove restrictions in the latest version of nginx?

Question

PHP

I have very frequent requests to nginx (php), the same application on Apache works fine, on nginx, after a few seconds, DDoS protection seems to work. What can limit? Config standard

Answer 1

Try to see how much the number of php-fpm processes in your configuration costs, by default there are 5. With this parameter, you also need to change a number of others, you can read more here or here
pm.max_children = 5

Answer 2

In the latest version of Nginx, as in all previous versions, there are no such restrictions.
If the application does not work as expected, it is incorrectly configured, but without seeing the config and without knowing what the goal is, it is impossible to say something specific.
