Installing luaJIT : no performance gain !

[Sylvain Fabre <sylvain.fabre@...>]

Hi all,
I just tried to replace ou vanilla lua51.dll with the luaJIT one.
After a few tests with some scripts, i have strictly no performance gain 
between both versions. Even worse : in some cases, luaJIT is slower than 
lua51.
I am sure to use the right LUA DLL, as the "jit" object exists when i 
link with luaJIT. I tried also to "force" the JIT system with 
jit.on(true, true) at the beginning of my tests scripts : no effect.

I guess that i forgot something at the installation or run level. Any idea ?
Or do you have a typical bench script, in order for me to be sure that i 
can reproduce the same environnement than in the benchmark page of luaJIT ?

Thanks for your help,

Rgds, Sylvain.
