Just for completeness, using that last function instead:
20046g, 66877p/g 0:00:01:00 0.00% 328.9g/s 21999Kp/s 21999Kc/s 1295GC/s
Not better in this test. Maybe I should do this after each test:
$ cut -d: -f2 ../run/john.pot | perl -e 'foreach (<>) { chomp; $l{length()}++ } foreach (sort keys %l) { printf("%d%10d\n", $_, $l{$_}) } '
0 1
1 7
2 7
3 275
4 653
5 1411
6 11667
7 5174
8 851
...and maybe I should do all tests with --max-len=10 as well. So many alternatives.
