Hello,
1) Optimize images on your site. It takes to much size https://prnt.sc/x4f9ws Use Tinypng service or plugin and it allows you to save up to 90% https://prnt.sc/x4f7ws
2) Minify and combine CSS and JS. We don’t have access to your cache plugin settings https://prnt.sc/x4fh2x So, can’t check it.
Regards
