Benchmarks
==========
# 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 particular benchmark, use a command
similar to that used to run individual unit tests. For example:
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 benchmark:
```
sky/tools/run_tests --debug -r expanded benchmark/gestures/velocity_tracker_bench.dart
/path/to/engine/src/out/Release/sky_shell packages/unit/benchmark/stocks/layout_bench.dart --package-root=packages/unit/package
```
(The `-r expanded` flag prints one line per test, which can be more helpful
than the default format when running individual tests.)
