Simple Instagram Super Slow

When I check my site speed with Simple Instagram installed, it is super slow. https://developers.google.com/speed/pagespeed/insights/

When I disable Simple Instagram and check the site speed again, it is cut in half. I went from 11 seconds to 5 seconds download. I think this is hurting my traffic and rank because things have taken a dip since installing this plugin. Is this true for anyone else?

I love the look of this plugin, so I’m hoping there’s a way to use it while speeding up the download a bit, like maybe a way to scale the images on or before load?
