how do you feel about the performance of the Kotlin (M5.1) compiler?
I am evaluating Kotlin M5.1 in a small project (currently about 15-20 classes). Hitting Build => Rebuild Project takes 11-14 seconds on a decent developer MacBook Pro Retina (2,6 GHz i7 CPU, 16GB RAM, SSD, JDK 7 current IntelliJ 12).
Is there something I can do to improve the compiler performance?
Or may I expect noticeable improvements in the future?
The Kotlin FAQ (http://confluence.jetbrains.com/display/Kotlin/FAQ) claims
The main design goals behind this project are [...] that compiles at least as fast as Java, [...]
Thanks for any input,
