I Agree with @fredgib at free.fr on -->

Note: Activating "Settings > Calc > Calculation > multi-thread" has no effect
and enabling OpenCL is not persistent after LibreOffice required restart.

-----------

Calc speed is not improved visibly since last 8 Yrs (since I started using it).
Here I am not discrediting any contributions done under the hood which may be
many! 

But net result for the user is not pleasing at all. In my system monitor (Linux
Mint) I always get one core stuck at 100% even if so called multithreading is
enabled ( I am on Libreoffice Version 7.1.4.2 )

For many of my Calculation intensive sheets and still prefer to copy-paste data
on Google sheet, Get calculation data from there and paste the result back to
Libreoffice calc. ... This takes pretty less time than applying same formulae
in calc itself !

Other strategy I am following is :-
> First disable "Autocalculate" from Data --> calculate --> Autocalculate
> Do all data inputs in your sheets
> Then once all data is in the place, do Data --> calculate --> Recalculate HARD
 OR press Shift+Ctrl+F9
> Now wait for considerable time ( from "Plant a coffee seed --- to ---> Have coffee !" )
> Finally it gets over .

------------------------------------------

So I will NOT say the basic issue is resolved and will not go with @Aron Budea
to "Consider" it Done.
