I don't know how long this has been available in Etrecheck Pro, but just found these in Etrecheck Pro Version 6.0.2 (6A004) analytics and thought they could be VERY useful in analyzing system performance problems
Analytics and
Storage. there is even more detail below these if you are really digging into a performance issue. Etrecheck is not creating this data rather it is digging it out, analyzing it, and displaying it in a useful format if not for technophobes at least for low-power users 😜.
