Thanks that helps.

One more question. Maybe this will end up having the same answer.. But 
let's say I have an object that I pass to the ruby extension. and all 
operations in the C code i'm doing are on that object passed using 
rb_funcall, rb_iv_get, etc. is it still seeing performance gains with C?

thanks
