Performance is worse


I set up Cloudflare DNS with a domain on Hostinger. However, the performance (Pagespeed Insights) is 80 and worse than without Cloudflare DNS. Are there settings I have to change?

Also, during setup I noticed the step “Always use HTTPS” was skipped. I didn’t change this setting to On. Should i? Also, my website was sort of down after I received the email that my domain was active. On my phone with with 4G it gave me “Too many redirect” errors. I switched from SSL Off to Full strict which resolved that specific issue.

Still, my website is slower. How could this be?
