As an admittedly biased Oracle architect/DBA, I'm inclined to believe that the "Oracle" bottleneck was due to the design/implementation of the Oracle DB, rather than the technology itself.<p>If, for instance, you were pulling this data out of an Oracle instance designed to be a cheap, historical archive, on minimal hardware and cheap disk, then yeah, it can be very limiting in performance.<p>If you're pulling it out of a production database, and have the priority levels set such that the data suck won't affect production users/usage, then again, that bottleneck is by design.<p>I'm taking that statement as something that's a comment on the system, rather than a slam on Oracle's technology and capabilities.
