My Nexus 5 is also sluggish in comparison to my iPhone. From the little research I did it has to do with the default webview used on Android. Hopefully this will also get better in future.

I work at Intel and we have the Crosswalk Project - https://crosswalk-project.org/ Even Google mentions using it for Android 4+ devices.

They could be bundling Crosswalk so any 4.0+ device would run the app in a Chrome 37+ WebView. Much better performance.
