In some cases if you have big blocks of voxels with the same properties,
compressed should be faster but it is strange ...
Maybe if your results are using visualization, regular is slower in
computing the voxels visualization properties ...

No, normally they are equal ! just that regular is supposed to be faster
than compressed (but I talk without visualization of course).
