Hi Ingo,
I'll get the results tomorrow as I'm now out of the office, but
I can perhaps answer some of your queries now.

These data may be much better for you. It's a single 15 second data
collection run only when the actual ray-tracing is happening. These
data do not therefore cover the data structure building phase.

I get my timings from ( I use RDTSC before and after the render
segment). The majority of the overall time taken for a run is
therefore data structure building. I do not time this.

I have (what is to me) a strange and very repeatable slowdown for a
CPU intensive benchmark on my system on newer kernels.
Hardware : Dell Precision 470.
CPU 2x2.0GHz Quad Core Xeon E5335 CPUs
Memory 4GB ECC RAM.
OS Ubuntu x86_64 7.10 (Gutsy Gibbon)

Modifying /proc/sys/kernel/sched_latency_ns to be double may have in
