With Racket 7.2, the following program takes >13 seconds to run on Windows, and <7 seconds on Linux either on Virtualbox on the same machine, or native Linux on another machine with slightly lower-powered processor:
#lang racket/base (define (fact n) (if (zero? n) 1 (* n (fact (- n 1))))) (time (void (fact 100000))) ; Windows native, i7-7660U ; cpu time: 13610 real time: 13633 gc time: 4459 ; Linux on Virtualbox, i7-7660U ; cpu time: 6691 real time: 6706 gc time: 1298 ; Linux native, i7-8500Y: ; cpu time: 6894 real time: 6882 gc time: 1129 While the difference is unlikely to matter in practice, given `fact 100000` is a very large number, I'm curious what accounts for this difference? Is it some big-integer library that Racket relies on? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
