I just played with Starburst ROM all night long last night and I have to say this is probably the best and fastest ROM for the Galaxy Tab 10.1. It’s based on the latest TouchWiz UX ROM minus the bloatware and speed additions.
My browser used to lag when I had Google Music on and browsed Facebook desktop version but after installing this ROM, all of the lag is completely gone. I’ve also gotten speeds near 2200 on Quadrant, which is much better than stock.
