[Kotlin/Native] Slow connection issues

i'm experiencing noticeable connection issues with Kord (branch feature/native on Linux). about 90% of interactions fail, i can't even defer them to respond later. so far i couldn't upload files too, and it takes 10 seconds for a message to be sent (and retrieved afterwards). what's strange is that it always takes 10 seconds. here's the code for the last part:

val (message, restLatency) = measureTimedValue {
    ctx.message.reply("Calculating...") // this is sent instantly though
}

message.edit {
    content = buildString {
        append("Gateway: ")
        appendLine(ctx.kord.gateway.averagePing ?: "unavailable")
        append("REST: ")
        append(restLatency)
    }
}

val (message, restLatency) = measureTimedValue {
    ctx.message.reply("Calculating...") // this is sent instantly though
}

message.edit {
    content = buildString {
        append("Gateway: ")
        appendLine(ctx.kord.gateway.averagePing ?: "unavailable")
        append("REST: ")
        append(restLatency)
    }
}

no such issues occur when i run on JVM. could this be related to Ktor, or maybe the curl engine itself?

Kord won't let me use the CIO engine either: TLS sessions are not supported on Native platform.

though the first 2-3 requests were fine

i dont even know whats going on anymore

you can try manually instrumenting the http client to rule out rate limiter problems but it’s most likely a curl problem

how would i do that?

viztea•2mo ago

custom plugin or i think Http call logging is an official one

is mine would need to remove the engine name thingy

did i just need to install it as a plugin? if so, here are the logs:
