Kotlin Native Compilation Time

I'm new to Kotlin Native, I just did a 'Hello World' and it took about 4s to compile, so I have the following questions:

• is this normal or there is something wrong with my system?
• is Kotlin Native production ready?

fun main() {
        print("hello world")
}

kotlinc-native SampleLinux.kt -o hello

btw I'm using Ubuntu 20.04 / 16GB ram / iCore 5

Thanks
