| # JavaScript Benchmark Performance Report |
| |
| _Generated on 2026-05-08 17:55:12_ |
| |
| ## How to Generate This Report |
| |
| ```bash |
| cd benchmarks/javascript |
| ./run.sh |
| ``` |
| |
| ## Benchmark Semantics |
| |
| The timed serializer loops use serializer-native typed values. Fory receives the pre-normalized Fory value used by its schema, protobuf receives the prebuilt protobuf-shaped value, and JSON receives the benchmark JavaScript object. Protobuf timings do not include `toProto`, `fromProto`, `protobufjs.create`, or `toObject` conversion work. |
| |
| ## Benchmark Plot |
| |
| The plot shows throughput (ops/sec); higher is better. |
