I reworked implementation of binascii.a2b_base64() and there is significant speedup:
$ python -m perf timeit --compare-to ~/tmp/cpython-master-venv/bin/python -s "from binascii import b2a_base64, a2b_base64; s = b2a_base64(1000 * b'b')" "a2b_base64(s)"
/home/sergey/tmp/cpython-master-venv/bin/python: ..................... 3.43 us +- 0.01 us
/home/sergey/tmp/cpython-dev-venv/bin/python: ..................... 1.52 us +- 0.01 us
Mean +- std dev: [/home/sergey/tmp/cpython-master-venv/bin/python] 3.43 us +- 0.01 us -> [/home/sergey/tmp/cpython-dev-venv/bin/python] 1.52 us +- 0.01 us: 2.26x faster (-56%)
$ python -m perf timeit --compare-to ~/tmp/cpython-master-venv/bin/python -s "from binascii import b2a_base64, a2b_base64; s = b2a_base64(1 * b'b')" "a2b_base64(s)"
/home/sergey/tmp/cpython-master-venv/bin/python: ..................... 76.0 ns +- 0.2 ns
/home/sergey/tmp/cpython-dev-venv/bin/python: ..................... 69.2 ns +- 0.1 ns
Mean +- std dev: [/home/sergey/tmp/cpython-master-venv/bin/python] 76.0 ns +- 0.2 ns -> [/home/sergey/tmp/cpython-dev-venv/bin/python] 69.2 ns +- 0.1 ns: 1.10x faster (-9%) |
