Hello! I want to make the site as quickly as possible , then I would know how to make 100 % static , because I see that would be the way of getting the wordpress but fast as possible . I wanted to know whether there are differences between. nginx fastcgi_cache vs wp_supercache or nginx fastcgi_cache vs w3 total cache is there any web tool that I can test both? simulate 5k users simultaneous browsing online ? so I can calculate consumption .
