I got bored and decided to benchmark string manipulation methods and how they affect the performance of a pandas data frame. As it is well-known, Pandas data frames act weirdly once they grow beyond a certain limit.

So, here is the experiment.
I created a data frame using Faker. The base data is the fake data of 100,000 rows.
