For your numbers, with Intel compiler, on i7 @ 3.33GHz, --benchmark is
Parser Time
Parse Time: 0 hours 0 minutes 0 seconds (0.543 seconds)
using 1 thread(s) with 0.471 CPU-seconds total
Bounding Time: 0 hours 0 minutes 0 seconds (0.000 seconds)
using 1 thread(s) with 0.000 CPU-seconds total
Render Time:
Photon Time: 0 hours 0 minutes 2 seconds (2.164 seconds)
using 15 thread(s) with 2.486 CPU-seconds total
Radiosity Time: No radiosity
Trace Time: 0 hours 2 minutes 8 seconds (128.999 seconds)
using 12 thread(s) with 1525.728 CPU-seconds total
Notice that hyperthreading is little help, as restricting to 6 rendering
threads is not a doubling operation:
Distinct 6 cores:
Render Time:
Photon Time: 0 hours 0 minutes 2 seconds (2.158 seconds)
using 9 thread(s) with 2.483 CPU-seconds total
Radiosity Time: No radiosity
Trace Time: 0 hours 2 minutes 38 seconds (158.196 seconds)
using 6 thread(s) with 943.581 CPU-seconds total
Same 3 cores:
Render Time:
Photon Time: 0 hours 0 minutes 2 seconds (2.160 seconds)
using 9 thread(s) with 2.483 CPU-seconds total
Radiosity Time: No radiosity
Trace Time: 0 hours 4 minutes 16 seconds (256.684 seconds)
using 6 thread(s) with 1532.217 CPU-seconds total
(cores-control with taskset command)

Hmm, the first time I ever used POV-Ray was on an ARM2 or ARM3 sometime
1990-1991... full circle!

It's really slow: 3 hours and it's only at 25%! Makes me wonder if it's even
using the FPU. I'm going to recompile and try again.

Ok, found the problem: Debian doesn't currently support the ARM FPU(s) in its
libraries yet!

Recompiled to use fp and cortex a9. Unfortunately it now seg faults half way
through the benchmark. It does this even if I decrease the resolution too.
Arrrgh!!!

Can you try that binary with a scene that doesn't use photons?

I just compiled a 3.6 binary instead. That one works fine.

I wonder how it would run on the $35 Raspberry Pi? The SoC is a Broadcom
BCM2835. This contains an ARM1176JZFS, with floating point, running at 700Mhz,
and a Videocore 4 GPU.

Anyone bought one of those yet?
They're currently expecting 11 weeks delivery time.

Just finished compiling 3.7rc6 on my RPi -- took about 6.5 hours. I
believe that a.out's use hardware floating point as the default. PovRay
runs but the image (make check) has some strange artifacts. I've
attached biscuit-RPi.png and the same image rendered on Win7x64. Here's
PovRay's output:
$ ./unix/povray +i./scenes/advanced/biscuit.pov +fn -d +p +v +w320 +h240
+a0.3 +L./include +obiscuit.png
