I've been trying all sorts of ways to "speed" it up. Logging in/out of gmail, different browsers, going through the blog link, etc. I guess you just get it when you get it, like the phone feature last week.
I've been using it for 2 days. I have it set up on 2 separate accounts. I'm still training it on what is a priority, but so far it seems to work well. It took a bit to get use to at first. But it is easy to switch between normal and priority mode.
