angular - Angular2 application using webpack is extremely slow in Edge browser -

my angular2 application extremely slow in edge browser. chrome , firefox comparably faster. when enabled production mode, faster in edge, there workaround rather using production mode. figured has "style loader". suggestions? have been trying figure out since 2 days.

my webpack.config file

    var webpack = require('webpack');     var htmlwebpackplugin = require('html-webpack-plugin');     var extracttextplugin = require('extract-text-webpack-plugin');     var helpers = require('./helpers');      module.exports = {        entry: {           'polyfills': './src/polyfills.ts',       'vendor': './src/vendor.ts',       'app': './src/main.ts'    },    // resolves extensionless files looking matching files .ts or .js extensions    resolve: {       extensions: ['.ts', '.js']    },     module: {       rules: [          {             test: /\.ts$/,             use: [                {                   loader: 'awesome-typescript-loader',                   options: { configfilename: helpers.root('tsconfig.json') }                },                'angular2-template-loader'             ]          },          {             test: /\.html$/,             use: 'html-loader'          },          {             test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,             use: 'file-loader?name=assets/[name].[hash].[ext]'          },          {             test: /\.css$/,             exclude: helpers.root('src', 'app'),             use: extracttextplugin.extract({ fallback: 'style-loader', use: 'css-loader?sourcemap' })          },          {             test: /\.css$/,             include: helpers.root('src', 'app'),             loader: 'raw-loader'          },          {             test: /\.scss$/,             use: [                {                   loader: "style-loader" // creates style nodes js strings                },                {                   loader: "css-loader?sourcemap" // translates css commonjs                },                {                   loader: "sass-loader?sourcemap" // compiles sass css                }             ]          }       ]    },     plugins: [       // workaround angular/angular#11580       new webpack.contextreplacementplugin(          // (\\|\/) piece accounts path separators in *nix , windows          /angular(\\|\/)core(\\|\/)@angular/,          helpers.root('./src'), // location of src          {} // map of routes       ),        new webpack.optimize.commonschunkplugin({          name: ['app', 'vendor', 'polyfills']       }),        new htmlwebpackplugin({          template: 'src/index.html'       }),        new webpack.provideplugin({          "window.jquery": "jquery",          $: "jquery",          "jquery": "jquery",          "chart": "chart.js"       }),    ] };
