By the way, have you heard about Dumbbench module on CPAN? It is a module that attempts to implement reasonably robust benchmarking, trying to find and discard bad runs (outliers):

It looks like those last two (10/11, 11/11) didn't made it to git mailing list, probably because of anti-spam size limits of email message on vger.

Do you have a public repository with this branch somewhere?
