Serhiy Storchaka added the comment:
Proposed minimal patch implements globbing in pathlib using os.scandir(). Here
are results of microbenchmarks:
$ ./python -m timeit -s "from pathlib import Path; p = Path()" --
"list(p.glob('**/*'))"
Unpatched: 598 msec per loop
Patched: 372 msec per loop
$ ./python -m timeit -s "from pathlib import Path; p = Path('/usr/')" --
"list(p.glob('lib*/**/*'))"
Unpatched: 1.33 sec per loop
Patched: 804 msec per loop
$ ./python -m timeit -s "from pathlib import Path; p = Path('/usr/')" --
"list(p.glob('lib*/**/'))"
Unpatched: 750 msec per loop
Patched: 180 msec per loop
See msg257954 in issue25596 for comparison with the glob module.
