Does the Win32 version of Nginx still have a performance advantage over Apache, even though it's considered to be in beta?

I have to put something--Apache or Nginx--in front of a NodeJS server on Windows. Using Apache means losing the single-threaded memory benefit of NodeJS, so I'm interested in Nginx. But if Nginx has no performance benefit over Apache when running on Windows, I'll just stick with Apache.

Any thoughts/advice would be appreciated.
