title: Incredibuild not very fast
body: <p>Our project takes a long time to compile, so I'm trying the trial version of Incredibuild.</p>
  
  <p>It is made of a solution of about 50 projects.</p>
  
  <p>The thing is, when I compile with incredibuild it doesn't go much faster, it may even last longer some times ...</p>
  
  <p>Here is a screenshot of the graph produced by incredibuild while build a subproject of the solution and it's dependencies, at times it appears to be doing absolutely nothing :

  <p>The build without incredibuild took 4 minutes, with it here 5 minutes, most often is falls to 3:30 like in the following case, but still with some gaps:

  <p><strong>Any idea what could cause this to happen?</strong></p>
  
  <p>note the problem is the same if I build the whole project</p>
  
  <p>btw the red line is cpu usage, green network in, and blue network out, as reported by incredibuild.</p>
  
  <p><strong>edit:</strong> just to be clear and since some people tend to focus on the low compile time of the examples above instead of trying to give a meaningful answer, a full rebuild of the project takes about 1 hour and half</p>
