But from my personal experience I can relate to that. When I see applications that seem to be too performant I often get the feeling that they might be phishing pages because they don’t do any actual work under the hood. So my first instinct is to avoid those kind of pages, even though it might be legit. > That's how you end up with software that's slow due to a million abstractions. How is an abstraction related to benchmarking? Those are too completely distinct topics. > Easily bench-marked bottlenecks can give you quick wins They can... but most of the time it is not a quick win. But the question is not about if it is quick win or not. The only thing that matters is if your are optimizing on the bottleneck or on something that has no measurable impact. Without benchmarking you are blind. > but that doesn't mean you should stop there or not have any foresight to optimize things ahead of time where it makes sense Yes, it does. When the bottleneck is gone, and the performance becomes good enough there is no further need to optimize. I am happily quoting Donald Knuth here "Premature optimization is the root of all evil." > Your cost benefit calculation also needs to take into account that optimizations decisions This is true. But it doesn’t only apply to optimizations. This applies to any kind of change you want to make to the code. So this has also been to considered when you want to build a new feature. The answer to that is: Optimize for change. Which is basically the fundamental idea working in an agile way, but most people don’t do this correctly. Optimize for change means you need a lot of test automation and clean code, so you can make any kind of code or architecture change quickly with low cost and low risk and without fear. I am practicing this since over a decade now and it works pretty good. |
