title: Effect of Screen Updating
body: <p>I have been playing around measuring code execution times to gauge differences between executing my scripts locally and on my server. At one point I forgot to disable <code>screen updating</code> and was thankful I'm not sensitive to flashing lights before thinking about it in more detail:</p>
  
  <p>When I first started using <code>VBA</code> I always assumed it was just used so that it didn't scare end users into thinking their PC was about to crash. When I started reading more into improving the efficiency of your code I understood what it was for but how much of an effect does <code>screen updating</code> really have on your codes execution time?</p>
