建议 Webpack 输出更多的日志，这样感觉起来会快一点，现在构建时就是一个静止的提示，看着比较沉闷，也会觉得比较满。

看来 Gmail 加了个进度条，让用户感觉快了，还真是不无道理。

在构建速度上，Roadhog（Weback 3）并没有比 atool-build（Webpack 1） 快，不知道 Webpack 4 会不会有质的提升，期待一下。

andriijas say 'There is no need to use the AutoDllPlugin'.
Is that means there's no need umi-plugin-dll if use webpack@4?

Related issue, with webpack@4, we could reduce the bundle size.

• Add sideEffects: false to react-router-dom package.json remix-run/react-router#6082
