angular - angular-如何减少 Angular 应用程序的 DOMContentLoaded 时间

Question

我正在练习角度并创建了一个应用程序，我只添加了 3 个组件。我的应用程序需要 26 秒才能加载，所以为了减少这个时间，我在我的应用程序中使用了延迟加载概念，但这仍然无法正常工作。实现延迟加载概念后，我仍然有 26 秒的时间来加载我的应用程序。

注意：我正在 3g 网络上测试我的应用程序。

请参阅屏幕截图以更好地理解

应用程序路由.module.ts：

import { NgModule } from '@angular/core';
import { Routes, RouterModule, PreloadAllModules } from '@angular/router';
import { MatTableModule } from '@angular/material/table'
import { FormsModule } from '@angular/forms';
import { MaterialModule } from './material/material.module';
import { MatFormFieldModule } from '@angular/material/form-field';


const routes:Routes=[
  {path:"pipes",
  loadChildren: () => import('src/app/pipe-module/pipe-mod.module').then(m => m.PipeModModule)},
  {path:"products",
  loadChildren: () => import('src/app/product-module/product-mod.module').then(m => m.ProductModModule)},
  {path:"users",
  loadChildren: () => import('src/app/user-module/user-mod.module').then(m => m.UserModModule)},
  {
    path: '',
    redirectTo: '',
    pathMatch: 'full'
  }
  
]

@NgModule({
  imports: [RouterModule.forRoot(routes),
    MatFormFieldModule
  ],
  exports: [RouterModule]
})
export class AppRoutingModule { }

包.json：

  }
}

一切正常，但我想尽可能减少我的应用程序的 DOMContentLoaded 时间
