I'm seeing only 156KB for the entire page+assets. The logo is SVG and the CSS is minified. Where are you seeing the additional data?

Sorry, click on the parent domain (the top corner link).

Other folks are looking at the material.io site as well. It's no where close to 5mb, it's < 150kb.

Here's my chrome network panel: http://i.imgur.com/kUqttf3.png

That screenshot is for material.io/components. Look at material.io.

Ah, my apologies. It wasn't clear because you originally referred to "four lines of text", and the marerial.io site has got about a dozen links and animations, but I do get your point.

It's still significantly closer to 800kb than 5mb, though: http://i.imgur.com/0fuGPwj.png

(I'm sure there's a better way to get the full size of the site than looking at all the requests and eyeballing the sum...)

It'll say the total in the bottom left corner of the network tab. 42 requests | 782 KB transferred.

112k here for a fresh load (no caching).
