Slow loading times

Hi, I have been reading around the forums but cannot seem to get a proper solution for this. I uploaded a module onto my LMS and there seems to be rather slow loading times whenever I click 'Next' or 'Prev', more so when I click 'Prev'. While it is loading, I can see a loading symbol as my mouse cursor.

I tried to remedy this by reducing the quality that it is published in. Even though loading times improved, the loading time is still quite noticeable. Less noticeable for clicking 'Next' but still more so when clicking 'Prev'.

I cant share the scorm package as it is for clients, but the size of it is around 12mb and there aren't any high-res images or a great deal of animation going on in each slide.
