Hi,
I suggest you to check this thread: https://www.8theme.com/topic/slow-load-times/
We use W3 Total cache plugin but if you prefer any other you can use it. Some special settings for this cache plugin you can find here https://www.8theme.com/topic/fixing-pagespeed-issues-once-and-for-all-could-apply-to-all-8themes-themes/
Also use optimized images.
Let us know,
Thanks, laranz.
