Target Audience: Intermediate to Expert Java developers, performance engineers, architects, and SREs who want data-driven insights rather than folklore. Summary Unlike typical Java performance books (e.g., Java Performance by Scott Oaks), this title emphasizes a quantitative, measurement-first methodology . It avoids blanket advice like “use StringBuilder everywhere” or “avoid streams for performance.” Instead, it builds a framework for forming hypotheses, designing microbenchmarks (using JMH), interpreting statistics, and understanding how JVM behaviors scale with load, data size, and concurrency.
