The RAM issue (if there was one) has nothing to do with the language in this case. If we are talking about lisp, then I assume we are referring to any true lisp, in which case the underlying hardware scenarios widely vary.<p>I don&#x27;t know how Arc does it but Clojure&#x27;s resources are no different than any of the millions of Java web servers running; just a much better language to run on vs Java for that platform.
