The comparison with AWS Lambda seems to ignore the AWS memory snapshot option called "SnapStart for Python". I'd be interested in seeing the timing comparison extended to include SnapStart.
In the linked detailed benchmark results they include Lambda SnapStart which seems to be faster than Cloudflare:
> AWS Lambda (No SnapStart) Mean Cold Start: 2.513s Data Points: 1008 > AWS Lambda (SnapStart) Mean Cold Start: 0.855s Data Points: 17 > Google Cloud Run Mean Cold Start: 3.030s Data Points: 394 > Cloudflare Workers Mean Cold Start: 1.004s Data Points: 981
"SnapStart for Python" costs extra though. If we are paying then you can even have prewarmed Python lambdas with no cold start on AWS (Provisioned Concurrency).
