It's time to test multithreading support in upcoming Scala Native 0.5.0! Let us know if you encounter any problems!
While we're still polishing the new minor version, you can try its current state in scala-cli or sbt.
Scala Native 0.5.0-SNAPSHOT is now available in Sonatype snapshots, so I decided to do a silly multi-threading comparison against regular JVM launcher (jvm-packaged), Native Image (jvm-native), and Scala Native in release-fast.
Even same ballpark would've been amazing!
