I don't know exactly why lua is faster.
maybe because in lua, I create one long gl command list (from glbegin to
glend) and in gem I trigger gemhead everytime I draw a square. is there
a way to make the gem part faster?

Resetting the gemhead is somewhat expensive as is calling glBegin()/End() pairs.  It is not surprising that lua is faster since it just calls the geometry.
