Is the performance of manipulating a single direcory with 45,000 entries
even something we care about? Who would ever put 45,000 files into a
single directory? Who would even put 100 files into a directory if getting
a directory listing takes two or more screens just to display?
my MH spam folder for the past 12.5 months contains approx 60000 files.
(time to clear it up.)
