Hmm, the first few scenes render ok, but you forgot to include hf.tga.
I haven't rendered the long ones yet (will do so tonight).
Here are the results so far for my PowerMac G3/300, 64 MB, virtual memory on
(note that this is _not_ based on the official compile, but the same
compiler with slightly different settings):
Test 1:
Time For Trace: 0 hours 0 minutes 5.0 seconds (5 seconds)
Total Time: 0 hours 0 minutes 5.0 seconds (5 seconds)
Test 2:
Time For Parse: 0 hours 0 minutes 2.0 seconds (2 seconds)
Time For Trace: 0 hours 0 minutes 12.0 seconds (12 seconds)
Test3:
Time For Trace: 0 hours 0 minutes 9.0 seconds (9 seconds)
Total Time: 0 hours 0 minutes 9.0 seconds (9 seconds)
Test 4:
Time For Trace: 0 hours 3 minutes 46.0 seconds (226 seconds)
Total Time: 0 hours 3 minutes 46.0 seconds (226 seconds)
Test 5:
Time For Trace: 0 hours 0 minutes 13.0 seconds (13 seconds)
Total Time: 0 hours 0 minutes 13.0 seconds (13 seconds)
Test 6:
Time For Trace: 0 hours 2 minutes 30.0 seconds (150 seconds)
Total Time: 0 hours 2 minutes 30.0 seconds (150 seconds)
Test 7:
Time For Trace: 0 hours 0 minutes 7.0 seconds (7 seconds)
Total Time: 0 hours 0 minutes 7.0 seconds (7 seconds)

Please ignore these numbers, they do ***not*** represent results with the
same settings (for some reason AA wasn't on...). Sorry!

And here are the corrected numbers:
Test 1:
Time For Trace: 0 hours 0 minutes 5.0 seconds (5 seconds)
Total Time: 0 hours 0 minutes 5.0 seconds (5 seconds)
Test 2:
Time For Parse: 0 hours 0 minutes 2.0 seconds (2 seconds)
Time For Trace: 0 hours 1 minutes 5.0 seconds (65 seconds)
Total Time: 0 hours 1 minutes 7.0 seconds (67 seconds)
Test 3:
Time For Trace: 0 hours 0 minutes 22.0 seconds (22 seconds)
Total Time: 0 hours 0 minutes 22.0 seconds (22 seconds)
Test 4:
Time For Trace: 0 hours 5 minutes 42.0 seconds (342 seconds)
Total Time: 0 hours 5 minutes 42.0 seconds (342 seconds)
Test 5:
Time For Trace: 0 hours 0 minutes 20.0 seconds (20 seconds)
Total Time: 0 hours 0 minutes 20.0 seconds (20 seconds)
Test 6:
Time For Trace: 0 hours 10 minutes 16.0 seconds (616 seconds)
Total Time: 0 hours 10 minutes 16.0 seconds (616 seconds)
Test 7:
Time For Trace: 0 hours 0 minutes 41.0 seconds (41 seconds)
Total Time: 0 hours 0 minutes 41.0 seconds (41 seconds)
One note on test 5 and 6: Mac compilers can optimise the lathe code much
better and are therefore much faster than PCs.
One major reason why (even when very few memory allocations occure) the Mac
version is slower is the way POV-Ray represents colors, vectors and almost
all basic types: arrays. The compilers do _not_ manage to use the 32
floating-point registers, instead they nearly always generate load/store
instructions so all the RISC benefits are gone :-(

It was intentional (I wanted to keep the size of the file small). You can
use any 512x512 24 bit tga you want for the heightfield and another image
(with equal dimensions) for the image map.

OK, however, I am not sure if this won't change the results (but I haven't
looked into the heigh-field code so it may not).

Hmm, it seems to matter. For test 10 I got 49 seconds and for test 11 156
seconds. Can you please make the hf and texture available, too?

It should matter - if the HF image is different, the shape is different, and
in most cases the number of intersections with the shape is different, too.
The texture image should have little effect, though.

I have experienced that too. Tried the standard Skyvase-benchtest and
under Win98 it took 1m 15s, and under DOS 1m 13s. Now if I could only
become competent enough to get Linux running properly... ;)
