Does this app make any network requests that might have their own cold start or caching effects?

2.5 seconds seems way too long to be attributed to the Worker cold start alone.

It makes requests to API server that is deployed to k8s, which doesn't have a cold start. Clearly, some caching by the runtime and framework is involved here.

My point is that "cold start" is often more than just booting VM instance.

And I noticed not everybody understands it. I used to have conversations in which people argue that there is no difference in deploying web frontend to Cloudflare vs a stateful solution because of this confusing advertisement.

Likely reusing http keep-alive connections.
