C-Ray was fired up as a ray-tracing benchmark and here Mandriva 2010.1 Alpha 3 was taking significantly longer to run than the rest of the competition. openSUSE 11.3 Milestone 3 produced the best result for C-Ray.

Ending out today's Linux testing was dcraw where PCLinuxOS again did the best followed by openSUSE and then Ubuntu. Results for Mandriva were not available.
