Events+ causing huge increase in site load time

I think the image says almost everything, aside from the very important fact that this site isn't even live yet. Therefore, there aren't any users RSVPing, buying tickets or posting any events. There is only one active event set up as a test, and I wasn't running any activity tests on it, nor are its tickets available to purchase.

Do you know what's going on with Events+ to cause it to run like this in the backend?

Also, is the "/?s" a Memberships query?
