[WP Smush Pro] No so much help from compressing images

I purchased your plugin to compress all images since I was having a very low performance rate at GTMETRIX and my site was running slow (still is) https://limebayattamarac.com/ BUT I am getting almost the same report results from GTMETRIX (see snapshot of test results here: https://limebayattamarac.com/wp-content/uploads/2018/05/limebayReport.png)

What am I doing wrong? My site weights 27.5MB , the same exact page load as before. Please help.
