(I've modified your benchmark to also test the case where data isn't
in the page cache).

Local ext3:
cached:
os.walk took 0.096s, scandir.walk took 0.030s -- 3.2x as fast
uncached:
os.walk took 0.320s, scandir.walk took 0.130s -- 2.5x as fast

NFSv3, 1Gb/s network:
cached:
os.walk took 0.220s, scandir.walk took 0.078s -- 2.8x as fast
uncached:
os.walk took 0.269s, scandir.walk took 0.139s -- 1.9x as fast
