有没有人能够复制纱（包pipe理器）声称性能？
上个星期我和一位朋友共进午餐，那位朋友自称是真棒纱，它的速度比npm快得多。 作为一个花费太多时间观看npm进度条的人，我只是使用我已有的项目进行比较。
https://yarnpkg.com/en/compare
在所有情况下，我先删除了node_modules文件夹。 我想纱线需要caching的机会，所以我第一次运行yarn install约7米10秒。 第二轮（我确实看到几乎没有时间）花了5分20秒。
跳回到npm已经有这些依赖关系cachef它花了差不多两分钟来运行npm install 。 所以我的结果与纱自己的比较页完全相反。
我是如何比较这些东西有什么深刻的缺陷？
这里是我的testing中安装的依赖关系：
