Angular 5 Webpack Очень Медленный

Question

Мы сталкиваемся с растущей проблемой, когда веб-пакет требует все больше и больше времени для сборки для производства (до 40 м сейчас, что намного выше приемлемого) для углового 5 (веб-пакет 3.11.0).

Я хотелвремя от времени происходит несколько отдельных вещей, но инструменты, которые я могу найти в Интернете, либо не работают с angular 5, либо не могут обрабатывать размер сгенерированного файла статистики.

Мой webpack.config

/*
 * Webpack (JavaScriptServices) with a few changes & updates
 * - This is to keep us inline with JSServices, and help those using that template to add things from this one
 *
 * Things updated or changed:
 * module -> rules []
 *    .ts$ test : Added 'angular2-router-loader' for lazy-loading in development
 *    added ...sharedModuleRules (for scss & font-awesome loaders)

К сожалению, я не очень разбираюсь в вебпаке и его работе (это основано на шаблоне, который подрядчик затем переработал для нас, а затем оставил безлюбые заметки / документация).
