In my image processing of cells it appears that 40% of the time is spend in the calculation of highlight

could you check how many times the processHighlights function is called? I don't think it's slow, but maybe it's called often. Does your view has many panzoom modules?

We have indeed 4 pan-zoom module in the view and the image have around 10 million pixels
