title: How to optimize this database and this query?
body: <p>I need to create a simple blog site where there are blogposts, users and comments.
  In homepage will be shown the blogposts and below users's comments with users's information:</p>
  
  <p>I have created 3 mysql table: blogpost, user, comment
