Performance guidelines - can we add them to the doc?

Hi! I'd really like to gather some performance guidelines somewhere.

TL;DR: How do I squeeze the performance when running TS+webpack(+react)?

Currently we're running a webpack + react + typescript (tsx files) project and with 1200 modules it takes around 2.5 minutes to compile. Could we document better in what way useBabel affects the build-process, in what cases transpileOnly affects tsc.

Is it possible to compile using all my cores? etc.

potentially https://github.com/amireh/happypack but seems, that it doesn't work with this loader

@krtr Yep, been looking at happypack but as you said it currently do not work with atl. Or webpack2 for that matter.

We saw great improvements in compile time (1.5x) by doing:

"awesomeTypescriptLoaderOptions": {
        "forkChecker": true,
        "useTranspileModule": true,
        "useBabel":true,
        "useCache":true
    }

and we also added ?cacheDirectory=.awcache on our babel-loader, which might also increased the perf.
