Full static wordpress?

Hello, I’m trying to make my wordpress 100% static, but could not have tested Redis and fastcgi cache? is there any specific way? I want the cache is unlimited, because I place cleaning by cronjob, I’m currently using Redis, but still has much consumption in mysql.

Image consumption!

Have you ever tried WP Super Cache with Preload mode? (dont forget to change php.conf into wpsc.conf then select “Use mod_rewrite to serve cache files” in Advanced Tab)
