How to set up a VPS for a WooCommerce online store?

Question

WordPress

Installed the WP Fast Cache caching plugin Installed nginx + php7.0
on the Memcached server The problem is those pages that are NOT cached by the plugin, if you hold down F5, you can put php. Yes, it is possible to make requests per second per 1ip. But it seems to me that you need to look towards caching on the server, and where exactly - there is not enough knowledge. It feels like you need to cache all .php pages before wordpress. Because admin panel is loaded in about 5 seconds. What needs to be installed on the server to load php pages faster?
