Thanks to you all we have 855 Downloads from SMPOV till today.

Has anyone tried if SMPOV can speed up "normal" renderings by using the
Intel PIV-"Hyperthreading"?

I've published some benchmarks with a Dual-Athlon System,here:
http://www.it-berater.org/shtmls/smpov_howto.shtml
where I get a Speedup from:


Single-CPU:
optics.pov rendered in 320x200 in 1 Tiles (-) from 07-09-2003 / 07:35:09 to
07-09-2003 / 07:38:34 (205 Seconds).

DUAL-CPU (2 tiles):
optics.pov rendered in 320x200 in 2 Tiles (V) from 07-09-2003 / 07:32:54 to
07-09-2003 / 07:35:01 (128 Seconds).

I'd like to know if someone has tried something like this with
"Hyperthreading" and can report if rendering shows a significant speedup or
not. I assume it should be less, then with two real CPU's IF POV-Ray keeps
the FPU's busy.
