Comment (by swissspidy):

 @Cybr Thanks! I'm sure folks, particularly from the core performance team,
 would really appreciate such an in-depth analysis. Especially since some
 people have also spent some time  looking at potentially slow functions
 like `file_exists`. I would recommend first collecting your findings in a
 Google doc or so and then sharing in the #core-performance channel. That
 makes it easier to discuss them and find synergies. Afterwards we can
 figure out the best path forward when it comes to creating tickets.
