You'll have to wait until December 6th to try the finished version of this update on the desktop, although you'll almost certainly get to try it earlier if you're willing to run pre-release code. Whatever you try, it's important to stress that this won't improve performance across the board. You'll mainly notice the difference if your device doesn't have much memory to start with, or if you're juggling Chrome alongside other apps (especially if you have many browser tabs open). Take heart if Chrome is still chewing up resources, though -- the V8 team still expects more improvements ahead, and it's particularly interested in lightening the load for entry-level devices with under 1GB of RAM.
