Why is the calculation speed so slow? It took 6 hours to calculate 100 cells and still no results. I am using a server with 1500 GB of memory, so insufficient computing power should not be an issue. The Python version I am using is 3.7. It seems like the calculation will never finish. Is there any issue that could be causing this?
