title: Java performance 64 bit
body: <p>I've recently moved to a 64 bit OS on Windows Server 2008 Enterprise.</p>
  
  <p>It seems that my java programs are running significantly slower than 32 bit on Windows 2003.</p>
  
  <p>Would really any feedback.</p>
  
  <p>Is this a known issue?
  Are there specific settings to improve performance?</p>
  
  <p>(I'm aware that there is a small performance penalty for moving to 64bit but I'm seeing a significant performance hit).</p>
