I've been similarly frustrated in the past. Interestingly, I've found that studying other engineering disciplines outside of software engineering to be best. The best explanations and modeling frameworks for concurrency I learned were from network engineering books and a couple hardware design classes I took. Re: principles around performance analysis and diagnostics, Brendan Gregg is a name you should look up. His book on systems performance is a tremendous resource in both principles and methodology. Even though it's not focused on coding specifically, the same principles apply.
