title: Apache vs. IIS PHP performance comparison
body: <p>Does anyone know of any links to realistic performance comparisons of IIS vs. Apache for PHP hosting?</p>
  
  <p>I am looking to utilise existing infrastructure for a change of technologies from .NET to a PHP application but I cannot find any information about PHP hosted on varying platforms. There is heaps out there about IIS vs. Apache in general, or ASP.NET vs PHP .. or any other language server vs server, language vs language but no server/language vs server/language.</p>
  
  <p>My current direction is to use PHP with FastCGI.. looks pretty good. Just need to justify it or find a <em>compelling</em> reason to reject the big cuddly MS monster that I'm used to.</p>
  
  <p><strong>UPDATED</strong></p>
  
  <p>Windows environment would be Win2k3 running IIS6 with FastCGI serving the PHP extension. Also planning to use eAccelerator or similar script cache.</p>
