I can’t see any documentation about how to configure Jetty from the conf file when using that as the engine? (I’m seeing relatively poor performance from Ktor relative to another jetty application which uses dropwizard and trying to see if it’s just running with some bad defaults)

For

Jetty

engine you can configure only common settings using a configuration file.

ah thanks - that’s a shame

I'm pretty sure you have the ability to fully configure Jetty, but in code, not through a config file. https://ktor.io/docs/engines.html#jetty-code
