There is a tradeoff. I say keep prepared those queries that are used on a
rather frequent basis. If they are only used infrequently or in a process
that isn't performance sensitive it would make sense to not keep them
prepared.
Also, since IBO does nothing to automatically Unprepare statements it would
be a good idea if ever there are things you do that you know are done for a
while to include code to explicitly unprepare the datasets and/or
statements.
It would be very interesting if you did some benchmarks and comparisons on
this.
