title: How to measure database performance?
body: <p>I'm developing a web app that will access and work with large amounts of data in a MySQL database, something like a dictionary/thesaurus. I need to test the performance of the DB as its size increases, so I know how slow each request will be in the future.</p>
  
  <p>Any ideas? Like are there specific tools to check DB performance for a particular query, etc?</p>
