Workaround Description: https://issues.jboss.org/browse/SOA-3559 There is a performance degradation in select queries from XML datasource. The workaround is to use an xquery expression that disables streaming (in other words, instead of '/a/b/c', use something like '/*[local-name()='a']/b/c'.) Only do this if the parsed footprint of the document is relatively small. project_key: SOA The eds_xmlfile_select scenario shows ~30% performance degradation in select queries from XML datasource. See the "(EDS) Files select - Charts" sheet of the document at [1] for details. [1] https://docspace.corp.redhat.com/docs/DOC-56368
Can we get the VDB and file used for in the test? Thx.
