 > Changing the order of preprocessors can also speed up your processing. For instance, if you want to extract a two-dimensional layer from a 3D field and re-grid it, the layer extraction should be done first. If you did it the other way around, then the regridding function would be applied to all the layers of your 3D cube and it would take much more time.
