First of all, thanks for the quick fix! It works like a charm!

I did 4 benchmarks, one for Big and Sentinel on the internal SSD. Big did it at 17fps, Sentinel at 11fps. I did another one for Sentinel on my Promise R4 raid0. As for fps, there was no difference with SSD. I did a 4th Sentinel benchmark, with the source on SSD and the DCP output to the external raid. That turned out to be slower at 10fps. Not sure if these are even useful comparisons, but I was kinda curious myself.

During the final phase of the conversion, the DCP has to be read back for hash calculation. That is probably somewhat slower from the RAID than from the very fast internal SSD. The J2K conversion itself, as the main task of the conversion, was probably exactly same speed for both runs.
