= Benchmarks This section compares the performance of Boost.JSON with two widely used libraries with similar functionality: RapidJSON which is known for its performance, and JSON for Modern C++ which is known for feature-richness. The bench program measures the throughput of parsing and serialization for the a set of JSON representing typical workloads. These implementations are evaluated:
