Try also other scenes. Last time I experimented with POV compiler i obtained
following cross situation:
- skyvase is faster on Linux then on Windows (about 20%)
- woodbox is faster on Windows then on Linux (about 15%)

skyvase is in my opinion obsolete benchmark because scene is quite simple
and on fast machines measures eficiency of underlaying IO subsystem, wchich
is on Linux faster :-)
woodbox is computationally more intensive and that is why Windows version is
better.

About 15%-20% improvement can be done with upgrade to newer Linux
distribution - newer gcc and gnu-lib:
woodbox under:
  RedHat 6.2 - 45 sec
  RedHat 7.0 - 35 sec
