I can now only test on Python3.6, providing much meaningful sentence,
still trying to use perf on cpython master branch.

---------------------------------------------------

$ python -m perf timeit -s 's="一件乒乓事事亏, 不乏串連产業, 万丈一争今为举, 其乎哀哉"*1000' -- 's.find("乎")'

Median +- std dev: 228 ns +- 7 ns


$ python -m perf timeit -s 's="一件乒乓事事亏, 不乏串連产業, 万丈一争今为举, 其乎哀哉"*1000' -- 's.find("乏")'  

Median +- std dev: 143 ns +- 3 ns
