I think the performance argument is huge as there are a lot of factors at play here. For one, people generally underestimate the performance cost of their choices. And that reaches from app code, to their db and their infrastructure. We’re talking orders of magnitude of compounding effects. Big constant factors that can dominate the calculation. Big multipliers on top. Horizontal scaling with all its dollar cost, limitations, complexity, maintenance cost and gotchas becomes a fix on top of something that shouldn’t be a problem in the first place.
