title: Benchmark function in Mysql ( Incredible results )
body: <p>I have 2 tables:</p>
  
  <p>author with 3 millions of rows.</p>
  
  <p>book   with 20 miles rows.</p>
  
  <p>.</p>
  
  <p>So I have benchmarked this query with a join:</p>
  
  <pre><code>SELECT BENCHMARK(100000000, 'SELECT book.title, author.name
  FROM `book` , `author` WHERE book.id = author.book_id ')
  </code></pre>
  
  <p>And this is the result:</p>
  
  <p>Query took 0.7438 sec</p>
  
  <p>ONLY 0.7438 seconds for 100 millions of query with a join ???</p>
  
  <p>Do I make some mistakes or this is the right result ?</p>
