The old implementation on trunk resulted in 5% overall slowdown in the page load time but we didn't quantify that until we removed the feature entirely last year.  That's probably because the feature was added over years as a pile of small changesets each of which introduced immeasurably small performance regressions.  Development in a branch allows a faithful performance comparison between the two.

This is great news!

All jokes aside, these are exciting features, but it’s important that we’re honest with ourselves about overall engine impact.
