Assessment of performance can be practiced and taught in the small. It’s really just about making decent estimates, testing and some profiling. There’s of course potential mastery here, specific knowledge and tooling, you can dig down almost indefinitely, but the basic motions can be taught with simple projects. You don’t need Google scale to encounter performance problems and potential improvements. I know this because I work on small scale things, and had to learn this kind of thing on the job. I can imagine a ton of educational projects that teach this. Complexity analysis and A&D are very useful when you need them, but they are just two of several tools.
