Cashing is alsoman, and it's one of the things which allows textual to be a fast so l r u, cash. Cashing and generating the key is done at the sea level, and so it's super fast. And you can use it for quite small functions. We've got a lot of calculations which pretty quick. You know, they're well under mill a second an like fractions of a mill a second. But if we introduce the l or u cashthe time it takes to do those function calls becomes the time it take to essentially do a a dictionary look up. So that that can a, that led to quite surprising speed ups.
