My website was loading normally before we moved it from HTTP to HTTPS, right around that time the website started to get heavy load time both on the front end and on the server bandwidth. I really don’t know what is the cause of it.
We have CloudFlare as CDN and Firewall, we also use Photon extension from WordPress JetPack plugin to host our cache images.
Our hosting provider analyzed and gave us the partial log that showed every single request spawned into 2 sub requests that cause our bandwidth to jump 3x.
Extracted from their conversation:
It does appear requests to the site are spawning two sub requests to the ajax calls. Below is from when I point my browser at https://www.nguoi-viet.com/hoa-ky/
