Our WordPress performance plugin, Lighthouse has been released and includes two new functions.

Scripts-to-footer function

As WordPress themes and plugins add JS scripts to footer, blocking page rendering, this option moves all correctly enqueued scripts (i.e. using the wp_enqueue_script() function) to footer. Note that it will not function as expected in all cases. If the theme has lots of scripts and dependencies, something might break. And, as Murphy says, if something can break, it will break.

Gravatar cache function

On an article-heavy site, using Gravatars can hurt performance a bit, as WordPress needs to connect to for every avatar to fetch it. This caching module saves a copy of the image on the server, and loads it 10 times faster next time, without the need for an external request. The cache expires in 14 days by default and is removed from the server in 90 days. Values can be changed to accommodate your needs.
