Performance Tools and Review Practices

A practical toolbox for performance work on the JVM: profilers, benchmarks, and Clojure-specific diagnostics.

Performance Tools and Review Practices focuses performance work on evidence rather than folklore.

Use the child pages as practical checkpoints for reviewing hot paths, memory pressure, concurrency decisions, interop boundaries, and production feedback loops.
