"We had shitty code, optimized it, now it runs [maybe] better" is probably the only fixture in software development. I'm not sure kind of code samples one would want in the context of an article as abstract as this one. I did not take anything from the article, but had a lot of "been there, done that" moments when skimming it. The difference between the OP an me: The OP wrote about it so others can learn, something I never did.
