Website Loading Very Slowly

Hello,

My website using the Enfold theme takes a long time to load.
I have adjusted the size and minimized every image that was uploaded on to the site. I even deactivated the Slider Revolution plugin which I presumed was resource hogging, but the loading time could still take up to 10 seconds.
Using Chrome Audit feature it told me there’s a lot of render-blocking script on the page. Could it be the issue from the theme?
Thanks in advance for your help.
