New submission from Марк Коренберг <socketp...@gmail.com>:
Big dirs are really slow to read at once. If user wants to read items one by
one like here:
--------------
for i in os.listdir()
use(i)
--------------
having generator will gain performance, as big directories often very
fragmented on disk. Also, dir_cache in kernel used more effectively.
