The WordPress cache is supercharged by the Servebolt hosting stack in multiple ways. Caching of static assets, like scripts, stylesheets and images is built-in by default, with optimal compression settings.
Caching of HTML can easily be enabled, and it also uses the cache systems already present in the hosting stack.
It is important to use server based caching for both performance, and scalability reasons. Using a PHP based caching plugin will never be as fast as relying on server caching. Server caches are many times more effective, and enable you to handle much larger amounts of traffic, compared to using normal WordPress plugins for caching.
WP Cache Plugin
The free Servebolt Cache Plugin for WordPress works for hosting stacks that conform to web standards. Instead of doing the caching in PHP, the plugin makes correct caching headers that enables the web server to cache HTML for you. This means that the NGINX web server will serve your cached HTML content, without hitting the slow PHP.

Servebolt Optimizer vs Caching Plugins
W3 Total Cache is a do-it-all plugin that adds a lot of code to your code base, the same goes for WP Rocket. WP Fastest Cache is also another PHP based cache plugin. All of these might be useful in non-optimized environments, but on hosting like Servebolt, they never deliver faster performance, than if you rely on server based caching.
