+# Benchmarks
+
+Benchmarks are set up for GeoJSON serialization and deserialization.
+
+## Running Benchmarks
+
+```shell
+./gradlew :geojson:benchmark
+```
+
+This will run benchmarks on the JVM, NodeJS, and Kotlin/Native.
+
+These benchmarks measure the time taken to serialize and deserialize a `FeatureCollection` containing 15,000 randomly
+generated features.
+See [GeoJsonBenchmark.kt](geojson/src/commonBench/kotlin/io/github/dellisd/spatialk/geojson/GeoJsonBenchmark.kt) for
+details.
+
+## Results
+
+All measurements are in ms/op (milliseconds per operation). Lower score is better.
+
+| Target              | Serialization         | Deserialization     |
+|---------------------|-----------------------|---------------------|
+| JVM                 | `834.176 ± 55.719`    | `77.700 ± 1.123`    |
+| JS                  | `3,287.40 ± 8.763`    | `423.472 ± 17.805`  |
+| Native (`linuxX64`) | `5624.209 ± 1242.046` | `993.008 ± 243.719` |
