bigint == horrible performance?by moodywoody (Novice) |

moodywoody has asked for the wisdom of the Perl Monks concerning the following question:
Dear Monks,
I was wondering whether there exist some general ideas of the performance impact when using bigint? I was putting together some snippets for projecteuler.net (yes, I was bored and uninspired). The 14th problem asks for the length of Collatz chains http://projecteuler.net/problem=14. Anyhow, I wrote that http://pastebin.com/jbYBFiRZ up. Or rather, at first I had one extra line at the top "use bigint;". Removing that line improved the performance from ~10min to 6sec or by factor 100. Am I missing something or is bigint incredibly slow? Thank you for your insights.
