Yes.

No.

The fully conformant configuration of the TPC-B benchmark is not
really suited for memory resident databases due to the amount of
stored data. As the benchmark should be run in 8 hours while each
transaction adds new data to the database the memory gets exhausted
rather rapidly.

I did not mean that Jesper should run the 8 hour configuration with a
fully populated database. Both the 'mnesia_tpcb' and 'bench' programs
are very flexible and can be used in many alternate configurations.
