Are you sure? I looked at Benchmark a while back trying to find a way to measure wall time with cmpthese() and couldn't find one. I don't think it does wall time comparisons in the iterations/second stats. > Anyway, the way the bench is designed, the i/o wait and other db overhead > should be exactly equal for each ORM .

I suppose it's hard to tell what should be measured here, since complex queries in Class::DBI typically mean hand-coded SQL or else manipulation in Perl, and anyone concerned about performance would probably choose the former. - Perrin ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
