You seem to have completely missed the part where the author said it was a real life scenario where he had to aggregate some data on a large dataset without making extra db calls. That’s exactly where you want to optimize for speed.

I just don't want to encourage less experienced developers to prematurely optimize.

Also, calling them "Performance Mistakes You Should Stop Doing" is a bit of a red herring in this case.  As it isn't something you should stop doing unless you need to for performance reasons (after you've determined it's an issue).

There are a couple down-votes and I didn't want to leave the impression that I was one of them.
