Maps Load Slow After Upgrade

I recently upgraded to 7.3.4 from .3 and since then the maps have loadied really slow.

I never used an api key before but did create one to see if that solved the issue but it didnt.

Is anyone else having the same problem and does anyone know of a possible fix?

Much appreciated.

I am just installing Web Analytics as the site is making requests and this could be slowing loading maps time if things are loaded by order? I'll see. 

Yep, that was the issue. Sorry and thanks.
