I guess the 'advanced O/R mapping tools' make it easier to map the data to an RDBMS, but their is still the performance issue. Since this has degenerated into a an issue of performance then I suggest the original poster create a clear interface between his data and its persistance method. This should make it easier to attach another, if his first choice is not up to it.
