As discussed in the comments, here are the most obvious changes you could make to speed up your build:

• UglifyJsPlugin and ExtractTextPlugin are very heavy in terms of their impact on your compilation time, while not actually presenting many tangible benefits in development. Check process.env.NODE_ENV in your config script, and enable/disable them depending on whether you're doing a production build or not.
  • In place of ExtractTextPlugin, you can use style-loader in development to inject CSS into the head of the HTML page. This can cause a brief flash of unstyled content (FOUC) when the page loads, but is much quicker to build.
• If you're not already, use webpack-dev-server rather than just running Webpack in watch mode - using the dev server compiles the files in memory instead of saving them to disk, which further decreases the compile times in development.
  • This does mean you'll have to manually run a build when you want to have the files written to disk, but you'll need to do that to switch to your production config anyway.
• Not sure if this has any impact on performance, but the resolve section of your config doesn't meaningfully differ from the defaults, and you should be able to remove it without causing any issues.
