Page Speed Online graduated out of Labs. There don't appear to be significant differences from the previous version aside from a restyling. Previous commentary:

When I ran the speed check on one of my sites, almost all the low priority problems listed referred to google ad urls.

That's proper irony.

More like accurate reporting? It makes sense that when you load an external Javascript file on the top or middle of the page would reduce your website's speed.

Yes, I'm glad they reported it, but I still find it amusing.

Similarly, Google Analytics apparently needs a longer TTL for their JavaScript. It was a couple of days instead of 2+ weeks.

I keep typing the urls into the "Search Google Developers". Seems like a bit of poor design there.

Seeing as it's labeled Search Google Developers, I would expect it to Search Google Developers and not to Analyze my Website. Seems fairly obvious...

True, but that requires reading. And reading is haaaaard.

After making a few optimizations, how do you get it to check again without having cached results? The refresh button still brings up the same issues that I've already fixed (mage size reduction, still shows old sizes, and expiry settings still reporting no expiry on files that a HEAD request confirms have expiry times).

Perhaps they are caching their results?

You could try modifying the URL a bit to try and trick in into thinking it's new (add a '?' or '/', pass some useless variables)

Seems to be caching individual file info for JS, CSS, and images, regardless of the page URL...

My JS is minified with Closure Compiler, but it still reports that "Minifying the following JavaScript resources could reduce their size by 7.2KiB (6% reduction)." What can be done?

Gtmetrix.com is better as the explanations are better and it can actually minify CSS, optimize images for you. Very helpful.

One of the ironic suggestions I got

    The following cacheable resources have a short freshness lifetime. 
    Specify an expiration at least one week in the future for the 
    following resources:
