- I had NGINX FastCGI page caching with Redis Object Caching. The problem was everytime we were purging entire cache, CPU usage was going 100% for a long period of time.
- Then I tried implementing Cloudflare Edge Caching and miracle happened.
- I downgraded plan from AMD 8vCPU to normal 4vCPU, still everything is fine.
Thank you Cloudflare
