webpack 问题， angular 通过 angular-CLi 打包优化--打包要近 40 分钟，请教如何优化

optimization.concatenateModules 卡在此处 79% 很长时间。一直在优化？代码写的太臃肿了？

win 10 4h8g 时间是 2600 秒左右===40 多分钟。

CentOS 4H8G 36 分钟完成

尝试过增加打包服务器配置（ CentOS 7 ），4 核 8G，8 核 16G 等都尝试过，甚至用了 16 核 32G 的电脑，没有明显的改善，用 2 核 4G 的服务器会导致服务器占用达到 100%而服务器瘫痪。

我的项目不算大，依赖的组件也不多，打包成功后，经压缩的 zip 文件是 3.6Mb 左右的大小。打包命令是 "bp8": "node --max_old_space_size=8000 ./node_modules/@angular/cli/bin/ng build --prod",
