Mentioning of Kotlin Native in context of Kotlin Compiler is completely not realistic, it's huge JVM application that cannot be rewritten easily on K/N
Not including that most probably performance would be much worse.
If we talking about startup time, you can try Kotlin Compiler compiled with AOT Excelsior compiler, but compile performance even for small scripts is only sometimes faster for small scripts and always slower on bigger projects.
So it's very naive to think that compiler performance is problem that cannot be solved by some magical "native" solution
