Im having big problems with events+ causing my website to slow down intermittantly

Ok so when i keep navigating through my website i tend to have fairly fast loading times. Then all of a sudden pages will load really slowly. After a short while this will speed up.

Now i notice if i disable the event+ plugin i never have slow loading times. I have tested this a lot and it must be something to do with event+ causing the issue but i don't know how to identify it. I have disabled all of the event + internal plugins and am still having the same issue.

Now as a side note when trying to add a map into a new event this feature does not work at all. i just get a loading sign when pressing on the globe.

any help would be really appreciated.
