not benchmarked, but size-text should be pretty fast.
there is a native os-function to do only size-calculation.
it needs text, font and some args.
i think /view takes the arguments from the face and calls it.
so instead of
size-text face/text face/font/name face/font/size ....
one simply can call [size-text face]
