As with any web app, the Devtools Timeline is your best friend when it comes to anything related to jank (rendering, scrolling, paint issues): https://developer.chrome.com/devtools/docs/timeline
The usual suspects are large paints on scrolling or doing extra work (layout, etc). Be sure to turn on "Show paint" rects to see where your time is being spent: https://developer.chrome.com/devtools/docs/rendering-settings There's also a ton of great content at http://jankfree.org/ to learn more.
