Strip ArcPy Libraries

Question

Hi,  Just wondering if anyone has ever investigated the idea of stripping down the arcpy libraries to decrease load time.  We have a few processing machines running scripts that only ever use a given set of geoprocessing tools.  Yet, presumably when arcpy loads, all libraries are loaded even though we are only using a small percentage.  Obviously the installation on the machines targeted could only be use for vetted processes afterward.

Well I for one would like to know why my startup time is up to 5 times longer than others and if there's anything I can do about it https://community.esri.com/message/913697-what-is-your-import-arcpy-overhead

If you are trying to reduce the memory footprint of the ArcPy session, well, you are out of luck.  It is true that loading ArcPy (ArcPy for Pro) takes a Python session from 15 MB to nearly 200 MB, but there isn't much you can do about it.  If you profile the memory usage of the Python session after loading ArcPy, you will see that a handful of DLLs counts for a vast majority of that increase, and those DLLs are fundamental to the operation of any ArcPy code.
