Ah, my bad. Are you aware of any benchmarks comparing v8 to LuaJIT? Looks like LuaJIT got removed from the alioth site (?).
"If you're interested in something not shown on the benchmarks game website then please take the program source code and the measurement scripts and publish your own measurements."
