title: Which framework should I use (Grails, Java/Spring)?
body: <p>I would like to create the back-end framework for my website using one of the following: Groovy Grails or Java.</p>
  
  <p>My main concern is scalability/performance and the app will  be able to handle large sets of data, primarily read heavy.  </p>
  
  <p>I will be using HTML5/JavaScript/Jquery for the front end and MySql but not hibernate spring JdbcTemplate</p>
  
  <p>Any info would be greatly appreciated, I am fluent with Java and Spring and have made a few small apps with Groovy/Grails.</p>
  
  <p>Edit: Some more specifications: I have to use java mails</p>
