Actually, ClojureCLR is also DLR-based, relying on Expression Trees V2, but not the hosting goodies. Thus, it might be runnable directly in .NET 4.0 without the DLR.
For ClojureCLR: Performance of the core libraries is quite good. Startup time is quite good. Of compiled Clojure code, not so good. The compiler is quite new and needs optimizing. Regarding benchmarking Clojure being discussed on the list: mostly I've seen comparisons of Clojure to other languages. There was a discussion of IKVM/Clojure performance some 11 months ago here: http://groups.google.com/group/clojure/browse_thread/thread/e48b64f3dc1f09fb I'd love to have good Clojure examples for benchmarking. For me, there are two aspects of benchmarking ClojureCLR against the JVM implementation. (1) How do the two compare in straight-up elapsed time comparisons? (2) How much of the difference is attributable to the implementations and how much to the platforms (JVM vs CLR)? The former is something I can work on, the latter is out of my control, other than finding compilation workarounds. Regarding platform benchmarks, I've not found much recent work. I've tracked down some older JVM/CLR benchmarks that are relevant and will be playing with them soon. Improving the performance of ClojureCLR is in the top two development goals. (Porting to Mono is the other.) -- David Miller On Jun 9, 8:31 pm, "John \"Z-Bo\" Zabroski" <johnzabro...@gmail.com> wrote: > I am basically in love with Clojure.
