I have recently been working with some hyperspectral rasters and have noticed that applying a stretch in ArcGIS Pro is very slow. I decided to perform some tests to get a speed benchmark. The rasters are 16.5 GB with 274 bands and I apply a Standard Deviation stretch. This process takes 3 minutes. I compared the process in ArcMap and the same size raster took. 1.68 seconds. If I bring the raster into Pro after calculating statistics in ArcMap, it displays instantly with no additional calculations needed. It would be beneficial if this task could be sped up.
