what's the fastest, most efficient way to write big string responses with ktor server netty engine (>200MB)?

[Big Chungus]

If it can be splitted into parts that can be fetched, build or constructed individually, I'd use channel response. This way you can start responding while still building the response

[bitkid]

its basically a really big sql result set

[spand]

respondWrite appears to be a streaming response:

suspend fun ApplicationCall.respondWrite(contentType: ContentType? = null, status: HttpStatusCode? = null, writer: suspend Writer.() -> Unit) {
    val message = WriterContent(writer, defaultTextContentType(contentType), status)
    return respond(message)
}

yeah, that's what i am using at the moment call.respondTextWriter in combination with a Sequence generated from sql result set
