smush reduced pagespeed score

Hello, since i installed smush and smushed all my images, my score now on pagespeed on gtmetrix is at 35% ( F) and saying this is due to "Serve scaled images" ...

on google pagespeed itself the site has a score of 91/100.. but on the gtmetrix plugin installed and on the gtmetrix website the yslow score is 75% and the pagespeed scrore is 35%

why is this happening?

    Hello Renee,

    Warning you see your results is because your theme is loading images larger than it's HTML holder, for example 500x500 thumbnails on on your home page but the actual HTML holder of that image is 300x300 so the image is resized with CSS to fit in that holder.

    Unfortunately this is not something Smush can deal with since the theme code is written in the way to call the larger image, and even though the image is compressed page speed tests don't like loading image larger than its holder, so this is something you need to check with the theme devs.

    kind regards,
    Kasia
