Documenttion for Calc multithreading

Hi

I’m trying to address a minimal user documentation for Calc Mutithread available at Tools - Options - LibreOffice Calc - Calculate - CPU Multithread.

Can one of help me to add contents on the subject? Where to get info, use case, tests, measurements…

Thanks

Probably asking devs who implemented it would be most straightforward, i.e. LLunak or DFrancis or MMeeks around Collabora, if still available.
