Introduction to jMetal:

Java optimization becomes easy when you shift your focus from complex, premature fine-tuning to high-impact, low-effort adjustments. Modern Java Virtual Machines (JVMs) are incredibly smart and perform heavy optimizations like Just-In-Time (JIT) compilation and escape analysis automatically.

By targeting the most common bottlenecks—memory allocations, string manipulations, and basic data types—you can dramatically speed up your applications with minimal code changes. 1. Optimize Memory and Data Types
