The XML Benchmark Tool (XBT) is an XML performance measurement tool, provided freely by Intel. It provides a framework that allows a user to analyze the performance of various XML processing engines such as the Intel® XML Software Suite, and compare the results. The XML Benchmark Tool allows performance testing of XML parsing (SAX and DOM), XSLT, XML Schema validation, and XPath operations. It is also extendable, allowing a user to write their own drivers to test other XML processing engines. The XML Benchmark Tool is currently supporting IA-32 architecture or compatible platforms and runs on Windows* and Linux* operating systems. The framework allows the testing of Java* and C++ based XML processing engines
