The old Ratrace Benchmark test gave me much slower results in version 9 (80 sec) compared to version 8 (47 sec). Am I doing something wrong?

Well the raytrace.lws does render slower in LW9 but it shouldn't be THAT much slower!

The first thing to check is how many threads you are using, LW9 works best with threads set to the number of processors you have, LW8 worked best with it set higher, if you have it set wrong it will slow down the render.

Check which camera you are using, I think I found Classic was the fastest for that scene. Unfortunately though the best I managed in LW9 was about 30% slower than LW8.5 I still feel there may be a bug in the Mac renderer because Windows is only about 5 - 10% slower in LW9 for that scene.

The old raytrace benchmark has a recursive reflection setup (a ring of mirrors around the scene) that the old renderer will do faster, as it does not handle recursive situations in the same manner as the new raytracer does.
