I remember various posts claiming such things but without any actual 
proove so it mostly stays an urban legend.

I made a quick comparison some time ago, for those who maintain an 
archive of povray.off-topic:

It showed a difference between the official Windows and Linux versions 
of about 10% in rendering the benchmark scene.  Note the test was far 
from sophisticated, various things (including beta version related 
issues) could have influenced the result.  Especially note that 
depending on the processor you might get similar speed differences from 
different compiler optimization settings on linux (see recent discussion 
in povray.unix).

So in the end it sums up to: Who wants to find a support for his OS 
decision in POV-Ray rendering performance will be able to find one (for 
whatever OS that might be).
