If anyone can run benchmark.py on Linux / NFS or similar, that'd be great. You'll probably have to lower DEPTH/NUMDIRS/NUMFILES first and then move the "benchtree" to the network file system to run it against that.

On a locally running VM: os.walk took 0.400s, scandir.walk took 0.120s -- 3.3x as fast

Same VM accessed from the host through a local sshfs: os.walk took 2.261s, scandir.walk took 2.055s -- 1.1x as fast

Same, but with "sshfs -o cache=no": os.walk took 24.060s, scandir.walk took 25.906s -- 0.9x as fast

Regards

Antoine.
