Pickle is fast for some cases

[monkwooo]

try this and see the output.
Would appreciate if you can explain me why test case in attached file shows pickle is faster while json is slower. [I do not understand what is happening here]. I merely stumbled onto this test case because of the use case in my project.

Pickle got faster than JSON over the years -- I updated the benchmark from the article for Python 3 and under Python 3.8, pickle runs faster. See https://github.com/dlukes/pickle-json-benchmark.

Another thing is that your benchmark may not be very robust, you should probably do multiple runs and average them :) Have a look at https://docs.python.org/3.8/library/timeit.html.
