Sadly it is seven years on from my original post and Acrobat still has the same amateur approach to multithreading. Nowadays every cpu produces is inundated with cores, yet Adobe appears to ignore this and this software remains in the dark ages. I would also add that OCR is no more reliable now than it was back then. I still routinely have to OCR large documents by page ranges of 500 pages, saving in between becuase I cannot trust the standalone 2020 "Pro" version I use to get through the three hours of processing (using the one core it knows about!) without crashing and losing progress.
