I think the rendering performance of individual Polymer apps/elements is going to hugely vary. For a simple UI element like polymer-ui-accordion<http://www.polymer-project.org/components/polymer-ui-accordion/smoke.html>, I'm seeing all paints complete in <1s.
If we're looking at the site, I'm seeing it take 3.5s for all rendering to complete, 2.10s for page load and 1.64s for DOMContentLoaded (good chunk of load is the sourcemap though - load is 1.8s without). It also has some very long animation frames: <https://lh5.googleusercontent.com/-P1bTWicYmXQ/Uu9oPh_za3I/AAAAAAAAGEg/DEe9HBdu-vE/s1600/Screenshot+from+2014-02-03+09%3A56%3A20.png> On Friday, 31 January 2014 22:59:30 UTC, Viet Hoa Dinh wrote: > > The issue occurs on both: > in Dart VM and in JS on Chromium. > > I’ll try to get some profiling numbers. > > I’m wondering if it’s the same issue that we can see right now on > http://www.polymer-project.org/: > the menus will appear after 2 sec (1.png vs 2.png). > And it’s probably more dramatic in Spark. > > -- > Hoa V.
