Page level Cache is active on Cloudflare as well as on server 32 MB RAM dedicated server with nginx, php7.2-fpm, memecached, wp super cache integrated with plesk pannel. All seems to be working alright, however when I check google page speed insigts it always says to improve server response time. Can someone look into this matter and guide me what is lacking in this setup. Below is the same page for your reference.
