Hello, 1) search issue tracker for openmp[1] reports for more details. There are different experiences. For me, it seems for me like it does not help on linux (and mac?) - just consumes the CPU. My experience[2] is that it helps on windows, but maybe it is the question of HW& SW configuration. To be on the safe side - OpenMP is turned off by default, so if somebody turns it on, such user/developer should be responsible for the consequences ;-)
2) I made some test with multithreading of tesserocr in python and it does not work for me. It works only with 1 thread (I never use multithreading, so maybe the problem is on my side.). Anyway expect and contribution in this area (OpenMP) is warmly welcomed.
