title: Console.WriteLine slow
body: <p>I run through millions of records and sometimes I have to debug using <code>Console.WriteLine</code> to see what is going on.</p>
  
  <p>However, <code>Console.WriteLine</code> is very slow, considerably slower than writing to a file.</p>
  
  <p>BUT it is very convenient - does anyone know of a way to speed it up?</p>
