That's what I was getting at in the end - your configuration is specific to your environment, and the tutorial should make a strong note of that, or provide an example that generalizes the optimization to a variety of environments.

I'm not sure how I read to others, but I wasn't trying to trash your set up so you know, just point out that it may not be suitable to others reading your tutorial. I can't live without sessions and reflection myself, but again I'm not saying that I'm the general public either.
