(Except for 2 logical cores, > where 3 threads were fastest, go figure...) Just redid my speed tests, which made me realize I'd remembered wrong. The shape drawing tests got max results with 4 worker threads but that for processing image files I get an extra 40% throughput with 8. (Scaling 4 megapixel image files at high quality by 0.4 and exporting to jpeg, I get a throughput of 82 images a second compared to 55 with 4) Faulty memory is faulty.
