I agree with you that the earlier you can catch those performance issues, the better. It's just like with catching bugs early in your development cycle. You could even argue that poor perf is a bug!

The more you know about the performance characteristics of your stack, the better, but given how many 3rd party services you might be using in production it might be close to impossible to predict that. Either way, you should be constantly monitoring the performance of your applications (backends, DBs, browser timings, RUM, cross-stack traces etc.) .

Looking forward to your Show HN on monitoring :)
