Results

A ratio greater than 1.0 denotes a possible regression (marked with ❌), while a ratio less
than 1.0 denotes a possible improvement (marked with ✅). Only significant results - results
that indicate possible regressions or improvements - are shown below (thus, an empty table means that all
benchmark results remained invariant between builds).

[meggart]

Looks good to me. Does mapCube work on Rasters with this change?

[lazarusA]

it does work. But, we still have the function caxes (doing the work at the saving stage), ideally this one should also be gone for good.

Another issue is that functions provided to mapCube only can be those acting on Arrays, hence Rasters function don't work, but that's another issue.

[meggart]

What is the status here? Can this be merged for now and we leave the remaining changes for later?

[lazarusA]

Merging this for now should be ok. I will not go into making those other changes anytime soon.
