I'm not sure I understand. Right now, the update methods run in parallel for sufficiently large inputs, otherwise serial. I'm still unsure whether their appetite for tasks should be throttled somewhat above and beyond the size limit. There's benefit to having CRC run 3x faster if it uses 4 threads to do it, but using 32 threads to run 9x faster is maybe not a win, even though it is nominally "faster". And here I mean "threads", not tasks, though I don't have a lot of visibility how much of a multiprocessor I am eating when I break something into 32 or 64 tasks. David
