XMach-1 was the first XML data management benchmark
designed for general applicability [1]. It is still the only benchmark
supporting a multi-user performance evaluation of XML database systems.
After a brief review of XMach-1 we summarize three additionally
proposed benchmarks (XMark, XOO7, Mbench) and provide a comparison
between these benchmarks. We then present experiences and
performance results from evaluating XML database systems with
XMach-1.
