title: Powershell loop performance / memory usage
body: <p>This might seem like a strange question but i'm really curious... I have the habit of making loops like this for example :</p>
  
  <pre><code>do { 
  start-sleep 1
  "anything"
  } until ($a) 
  </code></pre>
  
  <p>Instead of plain :</p>
  
  <pre><code>do { 
  "anything"
  } until ($a) 
  </code></pre>
  
  <p>Because I somehow have this feeling that if I don't use a quick sleep at every iteration, it will "spam" the command instantly a hundred times and affect performance. </p>
  
  <p>My question is, am I right in thinking like this or can I use it in it's plain form without worrying about excessive memory usage?</p>
  
  <p>I'm pretty sure i'm not but I developped an habit and would like your input on this ;)</p>
