| # Java JSON Benchmark Report |
| |
| The benchmark compares fory-json, Jackson, and Gson using the same data. The String group excludes |
| UTF-8 conversion. The UTF-8 bytes group uses direct byte-array APIs when available. Gson includes |
| String-to-UTF-8 encoding and UTF-8-to-String decoding. |
| |
| ```bash |
| cd benchmarks/java |
| ./run_json.sh --libs fory-json,jackson,gson |
| ``` |
