Yes, what I see is that the last thread needs endlessly . Process Lasso or Task manager showing that this last instance consumes much less RAM than the others, but the CPU consumption is even slightly more than the others.

I am running a strategy using the python bridge and calculating HMM (Hidden Markov Process) and PDA (Principal Component Analysis). What I am wondering, is that the other instances running fast.

I tried different number of cores:

At the moment,I am using Zorro only on the Intel i9 performance cores, but nothing has changed. I am doing this strategy with NumWFOCycle=5 and for each parallel run there is an on isolated core, no other activities . I put the other activities (non Zorro/Python) to Core 17 to 32.
