I'm going to put on VPS nginx, PHP 7 and Wordpress.
There are a lot of different plugins for this CMS and some of them are pretty crookedly written. I understand that the pursuit of every extra millisecond is usually a silly idea, but I recently discovered that the Ultimate Addons for Visual Composer plug-in created a huge load on the CPU, as a result of which the admin was loaded 6 times longer.
In general, I need a way to track the load on the processor and memory (or the relative percentage load) for each of the installed plugins. A few years ago, I used the P3 Plugin Profiler . But it has not been updated for a long time, and also does not support PHP 7. At the moment there are no alternative plugins.
Are there any extensions / modules for nginx or php that can complete the task? I heard about the New Relic service, but the prices there are very high.
