I see similar speedups, using the test suite:

On Linux:                                   On Cygwin 2.9.0:

in create-tests: time ./test-all.sh         in create-tests: time ./test-all.sh
  sh: 1225 sec                                sh: 27406 sec
  py: 155 sec                                 py: 2400 sec
  => about 8 times faster                   => more than 11 times faster

in import-tests: time ./test-wget2-1.sh     in import-tests: time 
./test-wget2-1.sh
  sh: 31.9 sec                                sh: 831 sec
  py: 0.35 sec                                py: 43 sec
  => more than 91 times faster              => more than 19 times faster
