So, I have

So, I have been pouring over my sites with hummingbird trying to get the page speed scores up. There are three areas that seem to really be sticking:
1. Image optimization
2. Render Blocking Resources
3. Server Response time.

Here's what's odd to me. Harrisburgcoc.com is currently a BLANK Wordpress install. I've only added a few plugins, including the WPMUDev suite, and a few others that they recommend.

Still, my scores for this site are pretty low on those two metrics, and I can't get them to come up.
Any help would be appreciated.
Thanks!
