Perf changes should have first become visible with the landing of bug 1554362. There was one quasi-automatically-reported perf improvement, on the Sheets raptor test: https://bugzilla.mozilla.org/show_bug.cgi?id=1554362#c19 If our tests do enough script-heavy things for the long-run memory improvements to be clearly visible, or if they run enough scripts that improvements to parsing are visible in big-picture takes, other improvements should be visible. I dropped a bunch of time on trying to finagle perfherder into revealing more changes a month ago, but I didn't get anywhere and ended up dropping it. The overall change is assuredly not Sheets-specific in any fashion, tho, so certainly more than just Sheets is affected by this.
