What causes most performance issues in software?

Network latency , slow DB queries, third-party delays, and unoptimized assets—not your core logic.

How to debug app performance bottlenecks ?

Measure with profilers first: Chrome Network tab, flame graphs, or OpenTelemetry. Isolate externals before refactoring code.

Will measuring fix slow code automatically?

No, but it reveals truths—often slashing times 5x by targeting real culprits like queries or images.
