Has anyone gotten graalvm native-image working with just ktor on any of the server engines (i.e. netty)? Someone gave me an example of it working with micronaut + ktor, but I haven’t been able to get it working with just ktor, as graal has lots of problems with netty it seems.

I've been using CIO with no issues. The main drawback with CIO is that it only supports HTTP/1.x (Not sure if that will be an issue on your side)

I’m using this inside of Cloud Run. I’m not 100% sure but I think it’s likely users aren’t making a direct connection to my server anyways.

You should be ok. It will be funnelled through the load balancer anyway so I would be surprised if anything goes down.

FYI - graalvm + ktor is fantastic. On cloud-run’s cheapest shared servers, I’m seeing cold server response times of 900 millis. That’s amazing I think.

Oh ya? Do you have a base template or something by any chance? This sounds amazing.

FYI - The day after, I started seeing startup times move from 900 millis to 1800 millis. Not clear to me why yet.

Thats quite odd... Same when you test it local?
