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