Nothing really new here. For example if you copy a million files for a folder it slows down as you get into the thousands of files in the folder.

There is no real fix for that issue but today you don't have folk taking the usual computer science and operating system classes so they just tell you it's slow but the eyes glaze over when you start explaining why.

Doctor, it hurts when I do "this"?

(Doctor) "Don't do that."
