What an odd result. I get times around 1.87 seconds for the autobox version and 1.68 seconds for the non-autobox version (Perl 5.10.0 with ithreads). On a second machine, I get 4.82 seconds for autobox and 4.32 seconds for non-autobox (Perl 5.10.1 without ithreads). A 10% penalty seems much more reasonable.
