I'm assuming there's something going on between the flash of the heart and the app render that's causing the slowness. By profiling in Chrome (Performance tab -> refresh) it looks like the animations are causing the issue. Having said that, as a user it feels reasonably fast and it's just the flashing content that's weird.
