Performace hummingbird + smush

Hello, my name is Denis i have recently purchased your subscription in hopes of smoothing out globaltechled.com I have taken over as marketing director and am having some issues. I have smushed all my images in media as well as all the images within my directory. I am still getting the same score i was before i started smushing.

As a secondary issue could hummingbird help me pinpoint the source of long loading times?

Best,
