same speed (or slighthly slower) than a hierarchical database was around
25 years ago, running on hardware that was current at the time.

-- normalization reduces redundancy, and given the cost of storage at
the time, redundancy was _expensive_ (even ignoring inflation, one month's rent on a 1.8 GB disk drive in 1982 would buy enough disks for quite a large RAID today). "
