Is LuaJIT really faster than every other JIT-ed dynamic languages?

According to the computer language benchmark game, the LuaJIT implementation seems to beat every other JIT-ed dynamic language (V8, Tracemonkey, PLT Scheme, Erlang HIPE) by an order of magnitude.

I know that these benchmarks are not representative (as they say: "Which programming language implementations have the fastest benchmark programs?"), but this is still really impressive.

In practice, is it really the case? Someone have tested that Lua implementation?

There's a good discussion at Lambda the Ultimate. LuaJIT is very good.

Many people have reported impressive speedups on lua-l (the lua mailing list). The speedups are most impressive for pure Lua code; the trace compiler is not as effective when there are lots of calls to C functions in loadable library modules.
