rel="preload" is certainly a good catch, but it seems that:« Omitting the 'as' attribute, or having an invalid value is equivalent to an XHR request, where the browser doesn’t know what it is fetching, and fetches it with a fairly low priority. »www.smashingmagazine.com/2016/02/preload-what-is-it-good-for/Furthermore, it seems strange that a production web app would fetch so many separated scripts, when minification/concatenation should have taken care of most of the assets in one request.
Where can I enable the "V8 internal metrics in timeline" as they are shown in the presentation?I have enabled "Developer tools experiments" but I don't see any experiment in dev-tools that would somehow be related to V8 internal metrics …
@Linus Lee: Yes. Current Chrome Canary: Version 57.0.2926.0 canary (64-bit) … is it working for you?
Jonas Bandi are you on chrome canary?
yaeh, same about paint time pane
this 'server push' thing keeps getting glossed over….how to make a server actually do that? does anyone know of a presentation that explains how that is done?
Hey David – if you use Node.js, check out this article that talks you through it – deanhume.com/Home/BlogPost/getting-started-with-http-2-and-server-push/10152
It depends on your server's technology stack. HTTP2 is not magic, its a protocol, so its mainly a matter of your http server supporting it. Chances are that you are either use nginx or apache. So take a look at these links:nginx: www.nginx.com/blog/http2-r7/apache: httpd.apache.org/docs/trunk/mod/mod_http2.html
