Hi all
What compiler optimization settings were used to compile the static Povray
Linux binary?
Is there a wiki/doc discussing this?
Thanks

The official binary was compiled using '-O3' and '-march=i586'.

You will find some discussion on the matter of the effect of compiler
optimization on POV-Ray performance in the past postings in these
newsgroups. On most x86 processors except the recent ones from Intel
(pentium 4/pentium M) there is only minor improvement to be gained by
use of more specific flags. For Intel you should make sure you use
'-march=pentium4'/'-march=pentium-m', the configure script handles this
automatically.

Unfortunately pentium-m is not yet specifically handled by configure
at the moment, so it might be neccessary to pass the proper compiler flags
to configure command-line <sigh>
