Chap 9 - SARIMAX loop on parameters run time

Hello,

I have a recent Lenovo T14s with an i7 processor and 64GB, so I assume I should expect above average performance.
The SARIMAX loop over the parameters has done 20% in 100mn.
I am running locally in VS Code.
Is that about normal or do you think I am doing something stupid?

EDIT: I stopped it after 6h and just 30% done.

Best regards,
