Use concurrency to hide I/O latency and improve throughput, not as a substitute for good algorithms.
Using Concurrency for Clojure Performance focuses performance work on evidence rather than folklore. Java engineers should read these lessons as a disciplined JVM optimization path: measure, isolate the constraint, choose the smallest useful change, and preserve readability unless the metric proves the trade-off.
Use the child pages as practical checkpoints for reviewing hot paths, memory pressure, concurrency decisions, interop boundaries, and production feedback loops.
