title: How can I troubleshoot multiple CC Graph Reduction events in Firefox that take a lot of time to complete?
body: <p>See image below.  I get multiple <code>CC Graph Reduction</code> events in a row, which slow down my page loading times tremendously.  I am not sure how to troubleshoot this, or where to look to minimize them.</p>
  
  <p>On a very high level I replaced some Form rendering code from procedural style to OO using Zend Form, but that in itself just generates HTML and does not do anything that I can think of that changes entire behavior of the application to where it was loading under 1 second and now takes over 4 seconds to load.</p>

  <p><strong>Update on case</strong>:  It seems that I have inadvertently turned on verbose logging (writing data to disk), which is perhaps the culprit of taking up the bulk of time spent as shown on the graph (in between the red CC marks)</p>
