Does a service worker compete for bandwidth?
<p>A service worker installs in the background, while the page is loading.</p>

<p>1) Does downloading of the service worker script happen in parallel with page load and delay the load?</p>

<p>2) Do the assets mentioned in install event get downloaded and cached in parallel with page load, or after page load event finished</p>

<p>3) Does caching of assets respect the HTML Native cache, or are they redownloaded every time?</p>
