From the site: The kind of binary format being considered for WebAssembly can be natively decoded much faster than JavaScript can be parsed (experiments show more than 20× faster). On mobile, large compiled codes can easily take 20–40 seconds just to parse, so native decoding (especially when combined with other techniques like streaming for better-than-gzip compression) is critical to providing a good cold-load user experience. – from the FAQ of WebAssembly If you build a website and have to parse something for 20-40 secs for a user, they should fire you on the spot for bad design. Start working for adult sites, if loads longer then 2 secs, redesign.

You are right only for the average website. If you are building applications delivered through the web, like games and advanced webmail, it can take a few seconds right now. With WebAssembly you could basically create all desktop applications on the web and it would be perfectly reasonable to take a few seconds to load one of them.

Gmail takes around 5 seconds to load over a 100mbit connection. Seems to not have posed any problem for them.

  2 and 5 seconds are far away from 20-40.

  Just because it works and makes money doesn't mean it isn't poorly designed. It may be that some people care about their users, more than their company's profit. Weird, I know.
