Until very recently using static typing frequently made the program slower.

Now the Groovy runtime is getting faster it's likely that in future using
static typing (especially if the type is a primitive) will make the program
run faster. I have an experimental dynamic runtime which executes
expressions almost twice as fast if the types of the variables are known and
are primitive,
