title: Why is Windows not considered suitable for real time systems/high performance servers?
body: <p>I hope this question isn't too subjective, but why is Windows considered an unsuitable operating system for real time systems and high performance servers? Are there any technical papers or studies that gauge it's performance compared to *nix alternatives?</p>
  
  <p>I've never actually heard any explanation of why developers are against using Windows for these types of systems, aside from the extremely common 'Windows is not a real time operating system' statement, as if it's some kind of well known fact that doesn't need to be justified.</p>
  
  <p>Note that I'm asking about Windows CE/Windows Server, not the desktop versions of the operating system.</p>
