Form submission really slow.

I’m using the Events Manager plugin with your Enfold theme and it looks great but when i submit and event booking i get the standard white box that appears and the thinking scroll appears signifying that the booking is being submitted. this is taking an abnormally long time (anywhere up to 20 seconds).

Can you tell me why this might be occurring please? I have used this event manager plugin before on other sites/themes and i’ve never had it do this delay thing… normally it’s done in about 2 seconds or so.

Any assistance you can provide would be greatly appreciated.
