Duration of the "Tests" step of https://github.com/python/cpython/pull/30890 

* GHA win32: 14 min 11 sec (test_peg_generator: 8 min 16 sec)
* GHA win64: 21 min 2 sec (test_peg_generator: 16 min 38 sec)
* Azure win32: 9 min 34 sec (test_peg_generator: 5 min 30 sec)
* Azure win64: 13 min 56 sec (test_peg_generator: 8 min 3 sec)

Duration of the "Tests" step of https://github.com/python/cpython/pull/31096 (which includes Gregory's change):

* GHA win32: 8 min 30 sec (test_peg_generator: 5 min 1 sec)
* GHA win64: 8 min 29 sec (test_peg_generator: 4 min 52 sec)
* Azure win32: 9 min 54 sec (test_peg_generator: 4 min 19 sec)
* Azure win64: 7 min 57 sec (test_peg_generator: 3 min 32 sec)

test_peg_generator is way faster, and the total tests duration is shorter especially the maximum time: 21 min (before) => 10 min (after).
