title: SQL Server: multiple queries or UNION
body: <p>I've 16 queries that I need to execute. All these queries have the same format : </p>
  
  <pre><code>SELECT string, number, number 
  </code></pre>
  
  <p>Make sense for me to group all these data together as it's to create a dashboard with all the results.</p>
  
  <p>My question is : do you think a <code>UNION ALL</code> will be faster then executing all the queries one by one?</p>
