As the title, {output : {comments:false}} and {comments:false} is not work in my project, webpack 2.2.0

Webpack compile process gets killed for example on AWS EC2 micro instance. Here is a question about it, it says that the plugin requires too much memory http://stackoverflow.com/questions/30747314/webpack-uglify-plugin-returns-killed-on-ubuntu

So how can we know how much memory the plugin uses?

你好。
从这段代码来看，读取缓存文件是不考虑option.sourceMap的，所以如果前后两次uglify如果设置的option.sourceMap不同，是否会有问题？

I am calling this plugin as following:

		new webpack.optimize.UglifyJsPlugin({
			compressor: {
				warnings: false,
				pure_getters: true,
	      unsafe: true,
	      unsafe_comps: true,
	      screw_ie8: true
			}
		}),

I end up that this plugin remove "!important" css property .

• Which arguments/options is responsible for that so I will remove (unsafe, unsafe_comps, ... or something else) ?

it does not seem to be supported now.
I mean it should always be true.

Does this library not support preamble?

new webpackUglifyJsPlugin({cacheFolder: __dirname, preamble: '// should be displayed on top of file'})

I am failing to get the banner

When running Webpack the current error is returned:
_new webpack.optimize.UglifyJsPlugin({
cacheFolder: path.resolve(_dirname, 'public/cached_uglify/'),
debug: true,
minimize: true,
sourceMap: false,
output: {
comments: false
},
compressor: {
warnings: false
}
})

I believe it to be just the let variable and probably an easy fix but I could not find it after googling different terms, Any help would be appreciated.

Thank you

(I can make a repo if needed)

new webpack.optimize.UglifyJsPlugin({
cacheFolder: path.resolve(__dirname, 'public/cached_uglify/'),
debug: true,
minimize: true,
sourceMap: false,
output: {
comments: false
},
compressor: {
warnings: false
}
})

Setup in webpack.config.js
new webpack.optimize.UglifyJsPlugin({ cacheFolder: path.resolve(__dirname, 'public/cached_uglify/'), debug: true, minimize: true, sourceMap: false, output: { comments: false }, compressor: { warnings: false } })

Does the following actually have an effect? I have seen it in examples, but can not find any documentation on it:

new webpack.optimize.UglifyJsPlugin({
        mangle: false,
        output: {
          comments: false,
          ascii_only: true
        },
        compress: {
          warnings: false
        }
      }),

It looks like this is a newer and faster version of an UglifyJS plugin, so I'm very interested to know more. What are the main differences between this and webpack.optimize.UglifyJsPlugin?
