Those Fly.io p99 latencies are atrocious. 2.6s P99 compared to CloudFlare 1.0s. Neither one seems particularly great at first glance, but the CloudFlare worker latency does seem on par with Lambda from previous experience (I have not tested Lambda@Edge or CloudFront Functions).

It's due to cold start on default preset when creating an app if you are running the app continuously it's good

I’m not familiar with the scaling behavior of Fly.io. Do you still hit cold starts on scale up?
