Engineer: AI agents turn performance optimization into a race — profiling first still wins
Abhishekcur · x · 2026-11-03
Developer Abhishekcur shares his performance workflow: 70-80% of time goes into profilers like flamegraph and perf, optimizing only where profiling shows it matters. He argues profile-guided optimization remains the most fundamental approach, and jokes that AI agents are turning optimization into a competitive race — doing more and more work rather than judging whether it's worth doing at all.
