Btw, another aspect of this is user expectations: where we previously were accustomed to the fact that listing files in a directory takes some perceptible time, we are now "spoiled rotten" by the speed of our CPUs and filesystems. So the overhead incurred by Emacs-specific processing, like reading from subprocesses, consing Lisp objects, and GC, which 20 years ago would be insignificant, is significant now, and users pay attention.
