Hello,
I added the variable OMP_THREAD_LIMIT as new environment variable and set it's value to 1 in both system and user environment and Tesseract still uses 4 threads. The OCR time did not change as well. So does this mean the limit only works on Linux?
Windows 10 latest version 2004, build 19041.508, Tesseract 5 alpha 64bit executable from "Tesseract at UB Mannheim" section
