That doesn't make that much difference. It's really the huge number of
packages that bites us, not the number of files per package.
One way to improve this would be copying the terminfo system, that is,
putting every file in a subdirectory that's just the first letter of the
filename. That reduces info to 26 subdirectories, each of which has a lot
less files than info has today.
There are other ways to do it, of course.
