Well, the fastest scripting language must be LuaJIT?

If you refer to http://shootout.alioth.debian.org/u32/luajit.php http://shootout.alioth.debian.org/u32/luajit.php my answer is: maybe. As far as I understand the JavaScript benchmarks there were made before the most recent speed improvements (JaegerMonkey, present in Firefox 4 beta). In my simple tests, the speed in some loops can reach the speed of C, with the times better than LuaJIT. Still, LuaJIT is easier to obtain and run, as far as I know.

  You can help by providing clear instructions on how to build the latest JavaScript engine.

    I'd also like to know. At the time as first JIT functioned in the browser I wasn't able to download the sources which really did JIT on Linux in the command line. I wouldn't be surprised that now again the latest speedup in the browser is not repeatable in the command line for most of the people.

    Thanks! LuaJIT really rules in the shootout. The tests I've done were only inside of Firefox 4 Beta and I've got 3.4 sec for 5M n-body on my slightly (30%) faster computer. I remember that traditionally the standalone builds of Mozilla JS were not giving the same results as the one in the browser. A message for Mozilla devs, in case anybody reads: be aware that people do try to measure how fast JS is from the command line and let them get the really last results! And use http://shootout.alioth.debian.org http://shootout.alioth.debian.org if you want to fundamentally improve your implementation of JS.

      Note the main n-body measurement is N=50,000,000. The source code was downloaded from the tracemonkey branch https://wiki.mozilla.org/JavaScript:New_to_SpiderMonkey https://wiki.mozilla.org/JavaScript:New_to_SpiderMonkey. They can do better than use the benchmarks game - Kraken is one attempt they are making to do better. http://krakenbenchmark.mozilla.com/index.html http://krakenbenchmark.mozilla.com/index.html

        Regarding sources, I know this: http://news.ycombinator.com/item?id=1754881 http://news.ycombinator.com/item?id=1754881 The benefits of the benchmarks game: allows comparison with other languages (like Lua) whereas as far as I understand their Kraken is JS only and browser only. Thanks a lot for your good work!
