TFA says "up to 30% faster!" i.e. not really enough to "prove [Python haters] wrong". I like Python, but program much more in Cython, because it's often tens or hundreds of times as fast.
p.s. Bruce Dawson's advice is that
You should never describe something as being a “90% improvement” or “90% better” – these phrases are meaningless. Instead, embrace the big and accurate 10-times as fast number. It’s 10 times better!
It starts with an example of a slow program -- slow_program.py, "the program I will be using for demonstration purposes" -- but then it immediately forgets about that. It goes on to describe "general ideas and strategies, which when used, can make a huge impact on performance" -- none of which apply to the demonstration program.
