Yeah I'm not talking about hundreds of thousands of requests, I'm talking about three developers and fifty code files. Which I thought I made eminently clear by talking about dev scaling in my posts rather than load scaling.
That isn't a "pseudo problem".
Of course it is otherwise PHP wouldn't have been so popular as it is even for more complex solutions.
That doesn't follow. Loads of software is written with inferior and suboptimal tools for all manner of reasons. Unix was first written in PDP assembler. That doesn't mean it was a good idea, it means it was done.
Popularity is a bad, bad metric of a tool's quality.
I have worked with people who make same claims as you resulting in us spending endless hours doing preparing for a scale that never happened.
Guess what our client felt about that invoice?
It's a pseudo problem, a theoretical problem, something that can be solved even though it might not be as elegant as the purists would like it to be. But it can be solved if it has to. Most often it doesn't.
