FOG6 is still laggy as hell. Any solutions?

I'm still getting massive amounts of unusable lag after having been on FOG6 for a while.

I don't think there have been any updates from TMO on this, has there?

Other people say their most recent Lollipop phones are running fine, even older ones with limited RAM, so it looks like Google has definitively fixed it with their most recent Lollipop?

Does the G500T have it yet?
