Not that I’m interested in using the Java platform :D but relevant comparisons between ABCL (Common Lisp on Java) and Clojure are rare. We just had a nice feedback on reddit, so here it is. The question was: After looking at the quite old benchmarks, ABCL seems to perform alright. Can anyone share their experience with ABCL in terms of performance, stability and memory usage? I wish I could give you more concrete numbers with an application you could test and see for yourself.
