Got it. What about initiating a 800mb image on a CPU limited virtual machine that THEN hits a database, before responding to a user request on a 300ms roundtrip? I think we need a new word to describe the average experience, stupidity doesn't fit.

I think there is just a current (I've seen it mostly in Jr engineers) that you should just ignore any aspect of performance until "later"

Reminds me of this quote which I recently found and like:
