I wonder if you good set up a standardized benchmark that you could crowdsource. The best would be a set of files that could be downloaded and a plug-in.

One of the things that I find takes the most time is when I run auto-tone on a group of files, then do the first change to the exposure.  I am using smart previews.

To me the ideal plug-in / script  would:

Make sure that it is in the specific test catalog
make sure the target directory is empty
possibly make sure the test catalog is empty

note start time
Import a standard set of files
note time
create smart previews
note time
auto tone
note time
Decrease highlights by one large click
note time
create 1:1 previews
note time
export full resolution jpegs
note time

A couple of things that would affect this:
The size of the catalog can dramatically affect import times as it checks for existing photos
it’s not linear, possibly order n^2
