Just wanted to drop a note and say I'm very impressed with the multicore 
support in 3.7RC3.

I ran the benchmark in 3.6 on my new system (Athlon X4 3.1 GHz quad-core) 
and it took about 13 minutes to render at 384x384.

With 3.7, it took about 2 minutes.  Oddly, though, I couldn't get it to 
display the output while it rendered.  Should +d work when rendering with 
multiple cores?

Jim

AFAIR you don't get output when running the built-in benchmark.

guess I didn't read it completely (old eye's I'd imagine) ... they say 
that's the 2nd thing to go ;-)

Hmmm, now to figure out why it doesn't here...

Ah, that might be part of the INI file - thanks.  That's a change from 
3.6, which did give me output.

No, no, memory's the second thing to go. ;)

Is it actually meaningful to compare the benchmarks of
3.6 and 3.7, or did the benchmark itself also change?

I did notice that the size of the benchmark image increased - it was 
384x384 with 3.6, and 512x512 with 3.7.

But in the end, what I was most interested in was seeing the difference 
between the two, and a reduction from 13 minutes to 2 minutes is 
significant. :)

There were some changes ... as already pointed out the image size was 
increased, and a text object "3.7" was added. IIRC there was also some 
photon tweaks done as well. I think a some point the built-in benchmark 
and the scene file had gotten out of sync with each other ... now they 
be the same.
