Re: Clojure performance on Android
On my team, we tried using RoboVM to compile Clojure to iOS. It worked fine once it booted, but startup time was a concern. We didn't spend a lot of time optimizing it though. We also found the compile/boot cycle to be quite long (over 50s to see a change). My understanding (perhaps mistaken) is RoboVM must compile all code before boot, so live-loading code via a REPL won't work. We switched to using Clojurescript/React Native and it's been a net positive for us so far, even though we had to rewrite some internal libraries for CLJS. We had a REPL briefly (Ambly, although we've recently had to drop support for it due to breaking changes from React Native upgrades) and our compile/boot cycle is about 20s. My coworker Chris Vermilion created these slides about our experience https://docs.google.com/viewer?a=v=forums=MTUyOTIzOTE0MjU1MDA0MDI3NjQBMTExMTI3MjYwMjc1OTc4MDg3MzQBXzVfV0tNdUZDQUFKATAuMQEBdjI Hope that helps, Ben On Tuesday, September 22, 2015 at 3:51:04 PM UTC-7, Roger Keays wrote: > > Hi all, > > Thanks for giving the world Clojure.

Clojure performance on Android
Hi all, Thanks for giving the world Clojure. It's already made my life better just by applying the idioms to my Java code (e.g. http://www.ninthavenue.com.au/java-with-no-design-patterns). I'm starting on a new project soon and would like to use Clojure, however in my experiments so far performance seems to be a bit of a problem. Since the project will target mobile devices performance is pretty important (especially startup time). To be honest, even for the server I'm a little deterred by the stats I've seen online of Clojure vs Java performance. I can always just write Java in a functional style and embed beanshell for a REPL. So I guess it would be good to hear from the community how things have worked out for them performance-wise, and especially on Android/iOS. Also, are there any known showstoppers compiling Clojure bytecode to iOS using RoboVM?
