Quoting “A game changer for interactive performance” by Vyacheslav Egorov and Erik Corry for The Chromium Blog:

Today we are announcing the release of Chrome’s new incremental garbage collector (GC) which dramatically improves interactive performance of web apps and HTML5 games.
...
Previously, garbage collection pause times depended on the amount of memory used. Therefore, large interactive apps were impacted by pauses that caused hiccuping. V8’s new GC reduces pause times dramatically[.]
...
In our testing the maximum time to render a frame including pause time is reduced from 272ms to 50ms.
For large memory sizes, don’t do everything at once, do it in several steps.
