I'm not sure if that is true. our application takes at least 100ms or more to parse. only parsing. on Safari 10.1.1 on a macbook pro 2013 late. well chrome and firefox is as slow as that. I don't think the same stuff in WebAssembly would take that long (i.e. angular 1 application, if we add angular 4 which we are planning it will prolly take even longer since we need more vendor stuff.)
