I believe he's talking about storing all files in the same directory,
which is simply The Wrong Way for a number of reasons. While saving a
large number of external files, we use a sub-dir structure in the form
/data/f4/d3/12/myfile.bin in order to spread the number of files in a
tree pseudorandomly. This is the same approach used by the Squid
webcache.
