As a benchmark, TPoX is used for the performance testing of database management systems that are capable of storing, searching, modifying and retrieving XML data.
TPoX was originally developed and tested by IBM and Intel, but became an open source project on SourceForge in January 2007.
The TPoX benchmark package contains the following: The TPoX workload consists of seven XML queries, two inserts, two deletes, and six XML update operations.
The primary performance metric of the benchmark is TTPS (TPoX Transactions Per Second) which is the throughput of the multi-user read/write workload at a given scale factor.
The smallest TPoX scale factor uses 10GB of raw XML documents, the largest uses 1PB of raw XML documents.
