Hi, was having the same issues on mine and found your post but no one replied yet- ended up trying a few things which have actually helped. First I just updated chrome and a bunch of other apps I haven't updated in a while, then decided to reboot (hadn't restarted in a while) and clean my system cache (like windows temp files from previous updates, apps, installs etc.).
To clear cache , had to go to Android boot menu, hold up volume key down while booting takes you to a menu, where there's a reset menu option - it looks ominous but just takes you to a sub menu. Make sure you only delete system cache! Other options may delete your data or OS! There's usually a "confirm" step so some safety there!
Upshot is it's now running much smoother in chrome and doesn't do the "just a moment" waiting crap when I push home button now- seems much quicker! Good as I love this tablets build but was about to toss it for being slow and laggy...
