    Actually there are a little more than 2000 files in /usr/bin, and
137 in /bin.

    Maybe I haven't read the thread with enough attention, but I
imagine that the filesystems are well organized to quickly find a file
from its filename. What takes more time is searching by wildcard because
it implies to scan all the directory entries, but the search happens in
the application, not in the filesystem.
