This is because you're using :noweb-ref, which _is_ slow, although you
apparently don't need it in the document. Use name keyword instead,
e.g.,
#+name: primetest
#+begin_src scheme :exports both :results output
(define (smallest-divisor n)
(find-divisor n 2))
(define (find-divisor n test-divisor)
(cond ((> (square test-divisor) n) n)
((divides? test-divisor n) test-divisor)
(else (find-divisor n (+ test-divisor 1)))))
(define (divides? a b) (= (remainder b a) 0))
(define (prime? n)
(= n (smallest-divisor n)))
#+end_src
Regards,
