Benchmarks: memory use can be as important as runtime for some applications
I often look to the benchmark game results. While I am pleased that Clojure is now included, I find the memory use (at least for these benchmark programs) to be disturbing (e.g., Clojure vs. Ruby 1.9 and Clojure vs. Java). When deploying to small servers, VPSs, small EC2 instances, etc. memory use can be critical.
