This website has been smushed. http://cleverworks.com.au
However the page load speed is still 8.72s
The GTMETRIX report here http://gtmetrix.com/reports/cleverworks.com.au/7cfifuGg
Says that Smush did not decrease the file size of wordpress generated thumbnails.
Also, the front page of Cleverworks is running a Marketpress products shortcode.
Are the page load speed issues caused by Marketpress or WP Smush Pro?
