Here's an example where scrolling is unusably janky on OSX, with a retina screen:

When I plugged in my external non-retina monitor to reduce, the jank is almost gone entirely--but it's still not as smooth as Chrome.

There's a single CSS class in this reduced version of that blog page:

.post-outer {
border: dotted 1px #ccbb99;
box-shadow: 0 0 0 rgba(0, 0, 0, .1);
}
