When I click on the menu item it takes too much time to load

This is my app-routing-modules.ts

const routes: Routes = [
  {
    path: '',
    children: [
      {
        path: 'login',
        loadChildren: () => import('./pages/login/login.module').then(m => m.LoginModule)
      },
      {
        path: 'products',
        loadChildren: () => import('./pages/products/products.module').then(m => m.ProductsModule)
      },
      {
        path: 'retailer-home',
        loadChildren: () => import('./pages/retailer-home/retailer-home.module').then(m => m.RetailerHomeModule)
      },
   ]
  }
];

This is my product-routing-module.ts

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { ProductsComponent } from './products.component';

const routes: Routes = [
  { path: '', component: ProductsComponent }
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule],
})
export class ProductsRoutingModule {}

First time when I clicked on the menu it took too much time to load.

This is Network tab
