These are some notes on how to load and process data efficiently.
Reduce before assembling¶
Assembling detector images (see Detector geometry reference) is relatively slow. If your analysis involves a reduction step like summing or averaging over a number of images, try to do this on the data from separate modules before assembling them into images.
This also applies more generally: if a step in your processing makes the data smaller, you want to do that step as near the start as possible.
