site and dashboard slow

Hi,

I’m finding the site and dashboard to be quite slow in comparison to some other premium/resource-heavy themes I’m running on other sites. Problem site in question is: http://precisionadvisory.com.au/

It often takes at least 6-7 seconds of the spinning preloader, before the page actually initiates or does anything when jumping between pages on the site. Sometimes it can load quite quickly but for majority of the time, it takes at least 6-7 seconds before anything happens, sometimes as long as 8-9 seconds, which is pretty bad. So for the average visitor they’d probably be wondering if their internet is broken. This also seems to be affecting the websites bounce rate.

This was an issue that I brought up originally but never really had the time to get into it but it’s really starting to bug me and affecting customers client experience.

Do you have any idea what the problem is or what we can do to resolve?
