If anyone is interested, I’ve re-run micro benchmarks for 14 versions of ClojureScript using Benchmark.js and the results are here:


These were run on a linux box on JSC/SpiderMonkey/v8 engines and they took 8hrs in total. All documentation for running them on your machine are here:


There is ability in the project to run quick benchmarks as well which take significantly less time (~ 2-3 minutes per cljs version)


@kamn: thanks! I need to so spend some time studying the results. there are some funky results. For example, the results for symbol benchmark . The strangeness disappears when I only run that benchmark. So ¯\(ツ)
