Not utilizing multithreading? #15

Open StephenHouse opened 1 year ago

StephenHouse commented 1 year ago

The plugin documentation on the ImageJ site says it is multithreaded ("more CPU cores means faster execution"), but when I run it, the plugin does not appear to be utilizing more than one core/thread, resulting in very slow processing. In Task Viewer, one thread is maxed, and occasionally another one might flicker to life, but otherwise the other threads are unutilized. RAM and (NVME) disk IO do not appear to be a bottleneck.

Operating System: Windows 11 CPU: dual Xeon 6230R (26T/52C apiece) Images: 16-bit, 1024 x 1024 px, .png Number of Images: ~25000

Thank you!
