I wonder if this operation is CPU bound at the moment.

A while ago I did some tests in DCP-o-matic to see how reel'd DCPs would benefit from multithreaded digest calculation. I don't remember exact numbers, but I think the outcome was small. It probably only makes sense at all if the DCP is sitting on an SSD. Parallel disc access on spinning discs is dead slow.

OK, thanks for the note.

Looks as if the hash checking efficiency is not exactly meeting common expectations... ;-)

This in the player, I have to check it in DCP-o-matic main for the digest computing.

I also wish there would be a little bit more verbosity during the checking - like immediately opening the report window that now only finally opens after the check, and listing the individual steps of the verification (e.g. which file or structure it is currently checking). The progress bar both in windows and OS X can easily be mistaken for a hanging application, as the verification takes long and there is no real progress bar growing.
