What OLS server limit (10 vcpu)

#1
I have a situation, with a VM with 10 VCPU and 32GB of RAM, with an average of 180 requests per second on this server.

However, WP-FORMS and Elementor are VERY slow, many times they don't even open pages for editing or creation, what and how to find out where the problem or bottleneck is?

The system load seems pretty low, does the load happens when the page loading slowly? Better to share the whole output of the `top` command so it may show more information during editing the elementor. Does the page loading issue only happens in the backend and not on the front page?

You could actually answer your own question. Just count the amount of plugins, then you have the answer. This is not an OLS problem, but a problem with Wordpress, or an unavoidable problem with any PHP framework. Reduce the number of plugins to a tolerable level. Then your performance problems will also be reduced.
