DBT-2 STP Results History for 2.6.0-test

DBT-2 is an on-line transaction processing (OLTP) workload based on the
TPC-C.  The following 2.6 history of results are from a 4-way system
with 4GB of memory using the AS elevator.  From 2.6.0-test5 to
2.6.0-test5-mm3, it looks like we have improved with about 500 more
blocks/s I/O with slightly less processor time.

The metric, NOTPM, is the number of "New Order" database transactions
per minute over a 20 minute run (bigger is better).  The "New Order
transactions" represent about 45% of the transactions of the workload
and is one of the five transactions in the workload.
