+# Benchmark notes for AIO
+
+## Snapshot info
+Repository: https://github.com/angular/angular (inside the `aio` folder)
+Commit: 268cf7989 docs: release notes for the v6.1.5 release
+
+## Running the benchmark
+
+```
+npm install
+npm run benchmark
+```
+
+## Modifications
+- Added devDependency `"@angular-devkit/benchmark": "file:../../dist/@angular-devkit_benchmark.tgz",`
+- Added devDependency `"@angular-devkit/build-angular": "file:../../dist/@angular-devkit_build-angular.tgz",`
+- Removed devDependency `"@angular-devkit/build-angular": "0.6.7",`
+- Removed npm script `"preinstall": "node ../tools/yarn/check-yarn.js",`
+- Added npm script `"benchmark": "benchmark --output-file=benchmark.log -- ng build --configuration=stable",`
+- Added artifacts from `yarn setup` to git (`/src/generated/` and `src/assets/js`)
+- Unignored artifacts from `yarn setup` in gitignore
+- Ignore `benchmark.log` in gitignore
+
+## Notes
+This benchmark does not run the `setup` script because it has prebuilt its artifacts (
+`/src/generated/` and `src/assets/js`).
+
+The original repository uses `yarn` instead of `npm`, but adding local file paths to `package.json`
+seems to make yarn hang so we used `npm` instead.
