With a 24,000 files directory on an SSD running Ubuntu,

     import os, time

listdir returns a list of na

     print("listdir:", time.time() - start)

     start = time.time()
     list(os.scandir("/home/bronger/.saves"))

scandir returns an iterator of DirEntry objects which contain more 
information than the mere name.

     print("scandir:", time.time() - start)

yields

listdir: 0.045470237731933594
scandir: 0.08043360710144043

So you are comparing apples and apple tarts.
