Hello,
We improved speed a little bit using Theme Options > Speed Optimization settings and W3 total cache plugin:
Before – https://gtmetrix.com/reports/petshopmontenegro.com/oUaweMHE/
After – https://gtmetrix.com/reports/petshopmontenegro.com/9dr6IqNT/
We don’t have more options in our theme to speed up the site. So, if you need any advanced help with personal site optimization you may contact WPKraken team.
Regards
