I am facing too much performance degradation from couple months. Finally I added new domain without Cloudflare proxy enabled and website is working perfect.
Without Cloudflare website reponse is 250ms to 350ms
With Cloudflare website response very from 650ms to 1800ms (huge difference)
I am using Cloudflare Pro for all my websites. I am also using Loadbalancer and Web Application Firewall.
Kindly confirm how to fix this issue and if there is any specific service that is causing this issue.
