Markyh,
That’s hard to say – there could be a multitude of reasons why the page speed tool changed. This plugin is really great at reducing perceived load times – that is, by placing your scripts at the bottom of the page the content and images load before all the scripts.
The alternative, where you scripts load first, can leave your content off the page longer making it seem to the user that it’s taking longer. However, by moving them to the bottom you’re not increasing the total load time – you’re prioritizing what loads first.
Usually the page speed tool will give you some tips on things you can do to reduce the page load time. You might find that a caching plugin or minify plugin works better than Script-to-Footer, for your application.
Hope that helps!
Joshua
