New TPoX release and performance numbers

[Seems like it is benchmark day today] Version 2.0 of the TPoX benchmark (Transaction Processing over XML) has been released. In an earlier post I explained what TPoX is and why it exists. The new release of the benchmark specification has some changes in how the data is generated as well as in some update statements of the workload. The workload driver has also been modified (its properties are now XML-based) to adapt it easierly.

What is also out since last month are TPoX performance results based on version 2.0. A 1 TB workload was tested against DB2 V9.7 on AIX 6.1 on a IBM BladeCenter JS43. The numbers were also compared against DB2 V9.5FP4 run on the same setup in the paper showing the benchmark details.

Please note that due to the changes in the benchmark specification, benchmark results from version 1.x cannot/should not be compared to those from version 2.0.
