A simple way to check (if ever you bother) if an option actually
does something, is to remove it, recompile, and compare the
binaries (diff -s new-povray old-povray). :-)

Sure, but who cares?
If it improves things, it stays; if not - out it goes.
Simple as that ;)

Any idea about a new POV classic-benchmarks for this kind
of studies about cpu/compilers/etc ?

I bet this has been discussed a lot of times. This is not
difficult in theory : one scene per pov object, scenes with
lots of reflexion/refraction, scenes with radiosity, scenes
with scripts that do lot of file I/O (where Linux seems to
shine more than Windows), etc. Then render all the images
and look at the time.
Look at the time... This is the problem. Because it is
likely to be much too long for the vast majority of
people.

Well, when some years ago I migrated to Linux, I haven't done it
*only* for speed reasons. When I tested some of my *real* scenes it
showed to be at least 5% faster on most scenes (with the official Linux
binaries and RH 6.2 standard) than the windows version, and practically
the same as the DOS version. But I've decided to use Linux for
raytracing mainly bcos I wanted stability. And that's what I got: lots
of stability. The best example is my last machine, and AMD 1.2Ghz: Linux
runs on it without any problem, but windows even refuses to install
(suwin errors). So, I don't care if it is faster, bcos it's not what I
look for... :)

I don't care (much) about the speed between the OSes. What I
wanted is top speed under Linux. Even if that top speed is
"worse" than Windows, I don't care. My experimentation was
how to bring the Linux version to maximum speed. Linux allows
you to easily recompile the programs in order to get better
performance, so why not do it? It was not yet another
Linux-is-better-that-xxx idea.
Sorry, the above paragraph is a bit confused, but I'm in
a hurry.
