Not quite. I was finally prodded into getting it working again just the other day, and I updated the Lua backend so that it uses the new Lua 5.2 goto statement. (It's not checked in yet.) Here are the new results of running the whetstone benchmark: gcc directly: 2582 clue -> LuaJIT: 2482 clue -> C -> gcc: 2361 clue -> Java: 784 clue -> Javascript: 105 clue -> Perl: 2.7 The top one is what you get if you compile the benchmark directly with gcc. I'm afraid I don't have a Lua interpreter value because I don't have a luasocket for Debian Lua 5.2 yet. The Javascript interpreter is V8. That's all very preliminary and may in fact be wrong --- it's all work in progress. Assuming the results are correct, the LuaJIT score is remarkable. Adding some more LuaJIT-specific optimisations --- using FFI types, for example --- ought to speed it up some more. -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ │ 𝕻𝖍'𝖓𝖌𝖑𝖚𝖎 𝖒𝖌𝖑𝖜'𝖓𝖆𝖋𝖍 𝕮𝖙𝖍𝖚𝖑𝖍𝖚 𝕽'𝖑𝖞𝖊𝖍 𝖜𝖌𝖆𝖍'𝖓𝖆𝖌𝖑 𝖋𝖍𝖙𝖆𝖌𝖓. │
