; Dumb benchmark to test the reporting of words marked during gc.
; Example: (foo 1000000)
(define (ballast bytes)
(do ((bytes bytes (- bytes 8))
(x '() (cons bytes x)))
((zero? bytes) x)))
(define (words-benchmark bytes0 bytes1)
(let ((x (ballast bytes0)))
(do ((bytes1 bytes1 (- bytes1 8)))
((not (positive? bytes1))
(car (last-pair x)))
(cons (car x) bytes1))))
(define (foo n)
(collect)
(display-memstats (memstats))
(run-benchmark "foo" (lambda () (words-benchmark 1000000 n)) 1)
(display-memstats (memstats)))
