Those function don't suffer from cold start time?

When somebody hit my webserver for the first time, how long are they gonna wait for the page to be loaded?

Assuming a noop in the functions part.

It uses clouflare workers, which is just spinning up v8 isolates, so there's no VM booting up. It's fast. They are also edge located. There are scenarios where using the kv or durable objects can cause a round trip back to the mothership, but not for reads.

Cold start is basically zero
I don't understand how...

I can understand almost zero time to start a worker, but how do they move the code?
