I mean the compilation and startup time that people think lies on the JVM, CLR, Dalvik and ART when trying to run Clojure code.

It sounds like you are referring to various ideas around delayed var loading to improve startup performance - most of that was delayed, although there was one change that improved compilation speed and improves the performance of some projects.

Yeah that was it, thanks.
