Well, then try the following script
my $max = 50000; my @l = ('a'..'z'); my @keys = map { join '', map $l[rand @l], 0..71 } 0..$max;
On my system running this script with a perlmalloc-built perl is 600x (!) faster than with a sysmalloc-built perl:
$ time /usr/local/src/perl-5.10.0-perlmalloc/perl -I/usr/local/src/per +l-5.10.0-perlmalloc/lib ~/trash/ 3.027u 0.435s 0:03.68 93.7% 1448+324155k 0+0io 0pf+0w $ time /usr/local/src/perl-5.10.0-sysmalloc/perl -I/usr/local/src/perl +-5.10.0-sysmalloc/lib ~/trash/ 405.090u 189.574s 13:01.52 76.0% 1466+495449k 0+0io 0pf+0w
This is a pathological case, but this may happen with FreeBSD's malloc.
