Hello,
We’ve changed some settings and results are better now – https://prnt.sc/1r3n0ia https://gtmetrix.com/reports/soqkorea.com/zwakbvaA/
Google Pagespeed (and now GTmetrix) always scores with 10-50 points mobile performance for 99% of websites built with WordPress. We suggest you test the site on real devices and you will see that there are no real performance problems.
And a question to your hosting provider, why your files http://prntscr.com/1r3neo9 do not come from CDN?
Regards
