Usually, when we use wordpress to write article, all contents are saved in mysql database. When we view our articles by browser, wordpress program will read one article from database,which will decrease loading page speed of our websites, meanwhile, it also increase pressure of our host server, especially for websites which have big traffic.
To solve this problem, we can change our article page into a html file, which will not read database and do not increase pressure of our host server.
If you are using wordpress, we can use WP Super Cache Plugin.
Step 1: Download WP Super Cache Plugin
You can download it from WP Super Cache,then you can install it.
