|  |  | Is there currently a way to benchmark the Linux binaries with variable
numbers of threads with the BETA release?  If so, can you send me the
command and possibly an INI?  This for a review that I'm working on for
LinuxHardware.org.  I have tried the old benchmark.ini which only seems to
spawn one thread (and I know it is said not to be compatible).  I also have
tried the -benchmark command.
Thanks,
Augustus

|  |  | So after a little more searching and testing, it seems that the
benchmark.pov simply does not run multi-threaded.  Would the following
command be a sufficient benchmark, changing the +wt value appropriately:
povray -i/usr/local/share/povray-3.7/scenes/advanced/abyss.pov -f +v +p
-w1600 -h1200 +a0.3 +wt8
Thanks,

  Are you sure radiosity is turned off?

	Not yet, but a couple of benchmark.pov and .ini files corresponding
to the benchmark currently available in povwin 3.7 beta will be released
with the next Linux beta.

	Not implemented in 3.7 yet.

	Abyss is not the most appropriate benchmark, but why not (actually
I've used it a lot to benchmark 3.6 too).
	+wt8 will let you start 8 render threads (are you by chance running
on a beast with 8 cpus? FWIW I've been benchmarking 3.7 on a 4x dual Opteron
lately, and the benchmark runs too fast to get good statistics!)

|  |  | Thank you for the feedback.  I really want to include the new POVRay in this
article I'm writing.  The article will compare a dual dual-core Opteron box
against a dual quad-core Xeon box (+wt8).  So, should I just go with what I
have here, or can you provide those new benchmark files?
Thanks,
Augustus

  You might actually also want to run povray with even more threads,
eg. 16 to see how it affects the rendering speed. It may well be that
you get a few percents faster renderings.
