angular 打包时间太长是否有可以通过参数来优化

新手上路，请多包涵

问题描述

angular-material框架的前端，通过打包命令进行打包发布，
采用8核8G内存的CentOS 7 来打包，
时间是28分钟===1671秒。
图片描述

我在本地windows 10电脑（4核8G内存）打包到一半时提示内存溢出而不成功，加上内存参数也是--max_old_space_size=4096之后打包也是。

用2核4G linux电脑打包不成功
图片描述

问题出现的环境背景及自己尝试过哪些方法

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。

打包命令是

"bp8": "node --max_old_space_size=8000 ./node_modules/@angular/cli/bin/ng build --prod",

我的问题和疑惑

打包后的经过压缩后的文件包.zip大小是3Mb,
请问这个打包耗时正常吗，是否有其他命令加以改进打包效率，
感谢指点。
