In terms of site speed, did you look over the LEAP recommendations?

For instance, there is an option to optimize jQuery, which you still need to do.
With LEAP, you can also remove ads above the fold, if that's what you prefer:
LEAP -> Optimize -> Script Execution -> Advanced Settings -> Disable Ads Above the Fold
And as discussed previously, you can also go to Ezoic Ads -> Ad Configuration / Ad Restrictions to manage ad placements and density.
Please keep in mind the number of ads per page is going to vary based on the user. Just because you are seeing more ads does not mean everyone else is seeing the same number of ads. The system takes user profiles and UX into account.
