Is decent, especially on smaller screens where fewer glyphs need to be rendered at a time, but can slow way down on big displays or during very fast scrolls. From looking at the timeline in Chrome's devtools, I can see enormous chunks of time getting devoted to layout after managing to outscroll the visible content, but it's not clear to me how to go about improving the situation.

Untested hunch: glyphs the browser doesn't know how to draw take significantly longer to layout than those it does?
