+## Benchmarking
+
+You can input `!bench-framework` or `!bench-module` in the comment area of ​​the PR to do benchmarking on `@modern-js/app-tools` and `@modern-js/module-tools` respectively (you need to have Collaborator and above permissions).
+
+You can focus on metrics related to build time and bundle size based on the comparison table output by comments to assist you in making relevant performance judgments and decisions.
+
+Dependencies installation-related metrics base on publishing process, so the data is relatively lagging and is for reference only.

+## Benchmarking
+
+你可以在 PR 的评论区中输入 `!bench-framework` 或 `!bench-module` 分别对 `@modern-js/app-tools` 和 `@modern-js/module-tools` 做性能测试（这需要你具有 Collaborator 及以上的权限）。
+
+你可以根据评论输出的对比表格，重点关注构建时间和产物体积相关的指标，辅助进行相关性能判断与决策。
+
+依赖安装相关指标由于需要前置的发包流程，因此数据相对有滞后性，仅供参考。
