Serialization Format Benchmark Suite

This repository contains a set of microbenchmarks comparing the performance of several popular JVM serialization formats. The goal is to provide realistic, reproducible measurements of:

• Serialization speed
• Deserialization speed
• Payload size
• CPU cost
• Memory pressure

The benchmarks are implemented using JMH (Java Microbenchmark Harness) to ensure statistically meaningful results.
