| |
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.
