Hi everybody I tried using LuaJit and Lua's performance increase but using the same option(Jit enabled or disabled at both languages) still Java execution time is better. About memory usage Lua is better than Java in both algorithms!
I post the results:
Lua normal execution
Whetstone: 1.453 seconds; memory usage: 31Kb
dhrystone: 7.625 seconds; memory usage: 92Kb
Lua using LuaJIT
Whetstone: 0.53 seconds; memory usage: 115Kb
Dhrystone: 2.452; memory usage: 139Kb
Java normal execution:
Whetstone: 0.125 seconds; memory usage: 180Kb
Dhrystone: 0.125 seconds; memory usage: 191Kb
Java using -Xint (without JIT)
Whetstone: 0.422 seconds; memory usage: 173Kb
Dhrystone: 5 seconds; memory usage: 185Kb

You can try "java -Xint" to run the Java's benchmarks with JIT
disabled (interpreted-only mode).
