Not quite the same thing. One major problem with having lots of entries in
a directory is for humans using it (who have not become significantly
faster or more capable over the recent decades.) Having lots of entries in
a single directory is simply very unwieldy. There are is a reason why
people invented hierarchichal files systems with directories and
sub-directories, you know.

For those situations where the directory is not intended to be looked at by
a human, but only by programs, then there are more efficient ways of storing
the data if you need that many entries. (A real database system, for
example.)


Besides, most (all?) of the situations where one might concievably want many
entries in a single directory, what one would usually want is lots of files,
not lots of sub-directories - once you start using sub-directories, you
might as well use more than a single level of them.
