I think you can back that up and say that anything > 5.8 is slower. In perl 5.10 they made major changes to the regex engine which must have added some overhead that now slows things down. I've seen instances, depending on the total number of rules running, of 50% slowdowns moving from 5.8 -> 5.10 and beyond. Michael > > - Julian
