Please don't take undue offence, but I don't think that your testing methodology sufficiently isolated the thing you were comparing. For example, your function for calculating factorials: define f (x) { if (x <= 1) return (1); return (f(x-1) * x); } Unless the tail recursion was optimized out of this, your result will likely be swamped by the overhead of much stack manipulation. And the fact that you used bc means that the the actual calculating is once or twice removed from the architecture. To be fair, you did recognize this in the last paragraph of your article. And I'm not saying that your comparisons have no value, just that their value is diminished for considering the difference between 32 and 64 bit processor architecture. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
