+# Performance
+
+To run these benchmarks:
+
+```
+npm run build:performance
+open ./performance/index.html
+```
+
+## Notes
+
+The components used in the render benchmarks are simple enough to be
+implemented by multiple styling libraries. The implementations are not
+equivalent but are useful for framing the relative performance of
+`react-native-web` against these tests.
+
+The implementations are not equivalent. For example, the `react-native-web`
+implementation of `View` does more than just styling. The
+`react-native-web/lite` variant implements a minimal `View` that allows for a
+more direct comparison with the `css-modules` baseline.
+
+## Benchmark results
+
+Typical render timings*: mean / two standard deviations
+
+Version: 0.0.73
