From my point of view, the root cause is CPU throttling on Cloudflare’s side because CDN tries to compress the file hundreds of times, but I need to prove it.
As Cloudflare Docs says - Cloudflare does not enforce response limits
https://developers.cloudflare.com/workers/platform/limits/#response-limits. Some limitations are described in Default Cache Behavior
https://developers.cloudflare.com/cache/about/default-cache-behavior#h_51422705-42d0-450d-8eb1-5321dcadb5bc, but no information about CPU.
What CPU limitations regarding requests processing Cloudflare CDN has?
Is there a possibility of upgrading my plan to remove the CPU limitations?
