Mac Pro Westmere RAW-file Processing with Canon Digital Photo Professional
Canon Digital Photo Professional 3.8.2.0 — convert to 16-bit uncompressed TIF
Canon Digital Photo Professional makes poor use of more than 3 cores.
However, by manually starting multiple batch workers, look at the huge gain possible on the 12-core!
Canon DPP is not using the available CPU very well, perhaps 1/3 of potential at most. But it is possible to run two batch jobs in parallel, which can soak up more cores.
