The JVM (Java Virtual Machine) is the engine that runs Java applications. Over the years, it has undergone many optimizations to improve performance, including:
JIT Compiler: The Just-In-Time (JIT) compiler translates bytecode into machine code at runtime, optimizing performance by compiling only the necessary parts of the program.
Garbage Collection (GC): Java’s garbage collection system automatically manages memory, freeing up resources when they’re no longer needed. The G1 Garbage Collector and ZGC (Z Garbage Collector) have improved both throughput and latency for applications with heavy memory usage.
Ahead-of-Time Compilation: GraalVM, introduced in recent years, allows Java programs to be compiled ahead-of-time, significantly improving startup times and reducing memory overhead, particularly for cloud and microservices-based applications.
