|There is a "-U" option on 'ls' that disables the sort and may be much faster.

|In any case, I'd avoid more than 1000 files per directory - irrespective of

If you can do without any formatting and sorting of the file list, the
quickest way to have a list of files is echo * . This is what I do when I
want to count files: echo * | wc -w . The con is that you have file names on
a long line, separated by spaces instead of line feeds.
