Hi torsten, also it's true that just having a lot more CPU cores doesn't speed up everything uniformly, there are only a few operations that are able to leverage multiple CPUs like mesh export and the display.

Things like boolean calculations will currently only use one of those cores - it takes a lot of specialized and very delicate work to make operations run on multiple CPU cores, the regular linear flow of a program has to instead be broken up into a large number of encapsulated work items so they can be handled separately by each core, it's pretty foreign to how regular coding tends to work although for some types of work like rendering tends to be more naturally suited to it.
