I have several python and PHP multi-threading scripts running on an old 2015 Mac el capitain OS with 4 cores that take only a few minutes each to complete.
Bought a 2018 18 core iMac pro running high Sierra and now those same scripts take 40 hours EACH to complete. Any hints what I can due to solve this problem? Anyone else, threading with php or python on high Sierra or an iMac pro?
Really dumbfounded right now.
I called apple and they said to wipe the system completely clean with a new install of the MAC OS system because the issue could be due to a conflict in software. I did that and it did fix the issue. So I will have to step through all my software installations to identify the one conflicting with the threading.
Threading in Python or PHP is 100 times slower on my 2018 18 core iMac
