[Python-Dev] Issue 11406: adding os.scandir(), a directory iterator returning stat-like info (original) (raw)

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

Thanks. I take it those are "USING FAST C version"?

What is "-o cache=no"? I'm guessing the last one isn't giving dirents, so my version is slightly slower than the built-in listdir/stat version due to building and calling methods on the DirEntry objects in Python. It should be no slower when it's all moved to C.
