The code is straight compiled, without optimizations. Therefore lite-C machine code is about 40% slower than machine code compiled with VC++ 5.0 with all optimizations activated.

You can test the performance with the mandelbrot program. It compiles under VC++ as well.

As to the comparision with LUA, Angelscript and so on, that are just interpreted scripting languages and not comparable to lite-C. lite-c is about 10 to 20 times faster and far more flexible and pwerful.
