- Subject: Installing luaJIT : no performance gain !

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
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,
