|Performance Profiling of XSLT Stylesheets and XQuery Documents|
Whether you are trying to identify a performance issue that is causing your production XSLT/XQuery transformation to not meet customer expectations or you are trying to proactively identify issues prior to deploying your XSLT/XQuery transformation, using the XSLT/XQuery profiler feature is essential to helping you save time and ultimately ensure a better performing, more scalable XSLT/XQuery transformation.
The XSLT/XQuery profiling feature can use any available XSLT/XQuery processors that could be used for debugging and it is available from the debugging perspective.
Enabling and disabling the profiler is controlled by the Profiler button from the debugger control toolbar. The XSLT/XQuery profiler is off by default. This option is not available during a debugger session so you should set it before starting the transformation.
