Ciao
un'pò alla volta sono riuscito a migliorare la velocità di caricamento della mia home ad 88/100, forse potrei già ritenermi soddisfatto dato che il mio sito è fatto con Joomla e la home di google è 94/100 ma vorrei capire se posso in qualche modo migliorare gli ultimi avvisi.
combine external javascript
There are 4 JavaScript files served from pagead2.googlesyndication.com. They should be combined into as few files as possible.

* http://pagead2.googlesyndication.com...js/graphics.js
