title: performance problem after adding machinekey in web.config
body: <p>Does adding a machinekey in the system.web of your web.config cause any performance problems?</p>
  
  <p>I added something like this to my web.config:</p>
  
  <pre><code>&lt;system.web&gt;
      &lt;machineKey validationKey="aaa"
      decryptionKey="bbb" validation="SHA1" /&gt;
  &lt;/system.web&gt;
  </code></pre>
  
  <p>and now it seems to run quite a bit slower. I am using firebug to see how fast the page is loading.</p>
  
  <p>I ended up with this problem after this <a href="https://stackoverflow.com/questions/851557/figuring-out-why-asp-net-authentication-ticket-is-expiring/873418#873418">issue</a></p>
  
  <p>Note: this is not the actual machine key I am using. I have a proper machine key.</p>
