this is really difficult to read, can you tell me which column am I looking at?
The first column is the searched pattern. The second column is the number of found matches (for control, it should be the same with all engines and versions). The third column, under the "re" header is the time in milliseconds. The column under the "str.find" header is the time of searching without using regular expressions.
PyPy 2.2 usually is significantly faster than CPython 2.7, except searching plain string with regular expression. But thanks to Flexible String Representation searching plain string with and without regular expression is faster on CPython 3.6.

It would be easier to read with a constant number of digits after the comma, so that numbers are better aligned.
