If you're referring to the 5× — 7× speed difference for Bocko I included at bottom of the article, I'd be interested in knowing as well. :) Perhaps nvbm (the author) could shed some light. I can only hazard to guess that JavaScriptCore is simply more heavily optimized to reduce startup latency, with this really paying off in the mobile environment.

It's confusing to me that Clojure running on Dalvik can be slower to start than ClojureScript running on Rhino running Dalvik.

I believe nvbm's demo running Bocko on Android using ClojureScript is actually using JavaScriptCore.

Rhino is indeed much slower; that's why Tahmid Sadik is motivated to covert Replicator to use JavaScriptCore over Rhino.

Here is nvbm's article on ClojureScript on Android: https://nvbn.github.io/2015/06/04/livecoding-android/

Not JavaScriptCore, just V8 inside a headless WebView.
