Will Rhino 7 or 8 support Multithreading? (Multiple CPUs for performance)

Will Rhino 7 or 8 support multiple CPU computation especially for working with large files?
At least for some critical commands like import, move, rotate to avoid waiting a long time when importing and moving with large files/objects?

Some things in Rhino ARE multithreaded, and probably more will be in the future. However, most of what you’ve listed there probably inherently can’t be multithreaded,or can’t reliably be so while actually being faster–there’s a lot of added overhead with multithreading! That’s the way most “content creation” tasks just are.
