I am trying to know the performance difference between mapping number column to long vs BigDecimal. I did following test.
Just as a side note and not a direct answer to your question:
the OJB performance will be very dependent on the RDBMS performance, especially when running tight loops with lots of data loading.
I.e. your test results will vary a lot depending on which database server your are using, JDBC-driver, indexes and/or clusters in the database etc. etc.
For example: you could find that OJB is faster with one column type on MySQL but get the other way around with Oracle (or even different versions on MySQL server).
