Java Performance Lab: 65 Hands-On Strategies to Debug, Tune, and Secure High-Traffic Enterprise Software
In the high-stakes world of enterprise Java development, where milliseconds mean millions in revenue and downtime spells disaster, Java Performance Lab is your ultimate hands-on playbook. Authored by performance engineering expert Mackenna Light, this 2025 edition delivers 65 battle-tested labs to transform your Java applications from sluggish to supersonic-optimized for Java 21's virtual threads, reactive streams, and beyond.
Dive into real-world challenges: Diagnose memory leaks with Java Flight Recorder (JFR), tame garbage collection pauses under 10ms, and scale microservices to 10,000+ RPS without breaking a sweat. From thread dump analysis in bursty loads to OWASP-aligned security tuning that won't tank your latency, each chapter blends theory with executable code, JMH benchmarks, and Kubernetes-ready deployments. Whether you're battling e-commerce Black Friday surges or financial trading volatility, these strategies ensure resilient, cost-efficient systems that thrive in AWS, GCP, or on-prem clusters.
What You'll Master:
- JVM Deep Dive: Memory layouts, G1GC/ZGC tuning, and metaspace leak hunting.
- Profiling Powerhouse: JVisualVM workflows, AsyncProfiler hot-spot detection, and real-time bottleneck tracing.
- Code & Concurrency Optimization: Loop unrolling, lock-free structures, and Project Loom's structured concurrency.
- Secure Scaling: Caching with Caffeine, load balancing in Istio, and Prometheus/Grafana dashboards for 99.99% uptime.
- Production-Ready Wins: Case studies slashing p99 latency by 70% in e-commerce and boosting throughput in fintech.
Perfect for senior developers, DevOps engineers, and architects eyeing SRE badges, this lab-driven guide includes quizzes, checklists, and a 90-day optimization roadmap. Deploy a tuned app by book's end and join thriving communities like the Java Performance Discord.
Why This Book? In 2025's AI-infused, edge-computing era, generic tutorials fall short. Java Performance Lab arms you with quantifiable wins-measure, iterate, conquer. Your high-traffic fortress awaits. Grab it now and engineer performance that scales with your ambition.
