OSDL has ported OSDL Database Test Suite 3(OSDL-DBT3) to PostgreSQL. It drives the database with an ad-hoc decision support workload. It helps database developers and users to identify database performance issues.
OSDL-DBT3 is derived from TPC-H benchmark. TPC-H is an ad-hoc decision support benchmark. It has 22 complicated queries doing a lot of table/index scanning, sorting and grouping by. Details about TPC-H can be found at: http://www.tpc.org/tpch/ Though OSDL-DBT3 is based on TPC-H, it deviates from TPC-H significantly. It skipped many of the requirements for audit purpose, as well as added flexibility. OSDL-DBT3 performance test results are not comparable to TPC-H results. OSDL-DBT3 tarball can be downloaded from: http://sourceforge.net/projects/osdldbt/ The source can be downloaded from source forge cvs tree and osdl bk tree http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/osdldbt/dbt3/ bk://developer.osdl.org/dbt3 OSDL-DBT3 is also implemented on OSDL Scalable Test Platform(STP). The platform provides a framework where users run a set of performance and scalability tests on various hardware platforms. Currently, OSDL-DBT3 is running against PostgreSQL 7.3.3 only. We plan to improve it so that it can run against PostgreSQL patches. To find more information about STP, visit: http://www.osdl.org/stp/.
