+## Benchmarking
+
+Though experimental, benchmarking scores are now available with [the dedicated benchmarking tool](./tool/benchmark/README.md) for the parsing.  
+On an AMD Ryzen 7 5800H @3.20GHz with g++11.4.0 in Ubuntu22.04 (WSL2), fkYAML parses [the YAML source](https://github.com/fktn-k/fkYAML/blob/develop/tool/benchmark/macos.yml) at a competitive speed compared against other existing YAML libraries for C/C++:
+
+| Benchmark                          | Release (MB/s) |
+| ---------------------------------- | -------------- |
+| fkYAML                             | 40.491         |
+| libfyaml                           | 31.110         |
+| rapidyaml<br>(with mutable buff)   | 147.221        |
+| rapidyaml<br>(with immutable buff) | 144.904        |
+| yaml-cpp                           | 7.397          |
+
+Although [rapidyaml](https://github.com/biojppm/rapidyaml) is in general 4x faster than fkYAML as it focuses on high performance, fkYAML is 30% faster than [libfyaml](https://github.com/pantoniou/libfyaml) and also 5.4x faster than [yaml-cpp](https://github.com/jbeder/yaml-cpp).  
+Note that, since fkYAML deserializes scalars into native booleans or integers during the parsing, the performance could be more faster in some real use cases.
