title: Speeding up WIX compiles
body: <p>I have a WIX 3.0 installer that is building 88 slightly different builds (cross product of 32 and 64-bit, 11 locales, four editions (Beta, Retail, Evaluation, Different Evaluation).</p>
  
  <p>Each build has slightly different contents in addition to localized UI, so I can't just build one configuration with multiple locales.</p>
  
  <p>The resulting MSI is about 120MB. I'm already using the CabCache.</p>
  
  <p>The installer takes about 3-5 minutes per release to build, resulting in a pretty lengthy overall build time.</p>
  
  <p>The install appears to be heavily disk bound during linking (light.exe).</p>
  
  <p>Clearly making the disks faster could help. Does anybody have advice on how to set up a machine that could crank through these installers faster? (or advice on reconfiguring my WIX project to build more efficiently?)</p>
