title: IF vs IIF and performance difference?
body: <p>I was wondering what is the difference between the <code>IF</code> statement vs the <code>IIF()</code> function in Tableau.  And then I found this page, which explained the syntax difference.</p>

  <p>But someone (over a seminar) also told me that <code>IIF()</code> has better performance.  Is that true?</p>
