Hi everyone...

I'm curious... I've compiled POV from source at home on my Slackware 9.0,
optimized for i586, and with options for sse, mmx and 3dnow (I have an
Athlon XP 1700+). Then I rendered two scenes - skyvase.pov and woodbox.pov -
to test its performance.

Skyvase takes 11 seconds on Linux, and 10 on Windows. Woodbox takes 20
seconds on Linux and 18 seconds on Windows.

The question is: any tips to further improve performance under Unix? Is
there anyone here that has POV running faster under Un*x at all?

And, what exactly are the optimizations on the Windows official version, and
with which compiler has it been built?

Thanks in advance,

Roberto

Intel compiler was used and settings are probably written in windows dedicated
source package. As far as I remember Intel cooperated with Chris Cason in
adjusting performance of POV-Ray made with their compiler.

Remark that you can get the Linux version of the Intel compiler for free
for non-commercial purposes:
http://developer.intel.com/software/products/compilers/clin/noncom.htm
Search the newsserver for good settings (for both gcc and icc).

I made some unofficial binaries with the gcc and the icc some times ago to
try to get the most out the compilers.

It's version 3.5a AFAIR. There are the options I used for gcc (the 3.1
version), unfortunately I haven't written down the ones for icc.
