title: Are CNAMES slow?
body: <p>I'm using CNAMEs together with S3/CloudFront to serve some static files like js, css, images, etc.</p>
  
  <p>I do it to make the bucket's URL pretty and because I think is better have all targeting to my site and in case in some future I want to move those files the change should be transparent. </p>
  
  <p>Today reading blogs I saw some think CNAMEs are evil for speed.</p>
  
  <p>So, what to think about it?</p>
