I chose the default limit so it doesn't get activated too often.
Specifically, it doesn't get activated in the emacs/lisp directory.
And I don't see any slow-down for the current limit on my laptop.
But it's a defcustom, so change it to suit your own needs.

For a local file system that is true -- but I have some directories
which have +25000 files, and in those your code takes a few seconds
to execute.
But it would make sense to use the above as an alternative or
alternative for e.g. windoze... I'll think about it!

Could you debug that?
