# Benchmarks This directory (and its sub-directories) contain benchmarks for Flutter. The reporting format for benchmarks is not standardized yet, so benchmarks here are typically run by hand. To run a benchmark: 1. Build `sky_shell` for Linux Release using the instructions in the [Engine repository](https://github.com/flutter/engine). 2. Run `pub get` in the `packages/unit` directory. 3. Run the benchmarks by running the following command from the root of the flutter repository (replacing `stocks/layout_bench.dart` with the path to whichever benchmark you want to run): ``` /path/to/engine/src/out/Release/sky_shell packages/unit/benchmark/stocks/layout_bench.dart --package-root=packages/unit/packages ```
