The chart below compares the performance of the XPLINK and non-XPLINK compiled versions of the V1R9 XML parser. Significant performance improvement is demonstrated in the XPLINK case. In order to avoid the overhead involved in XPLINK/non-XPLINK communication, the XPLINK parser was called from an XPLINK application and the non-XPLINK parser was called from a non-XPLINK application.
A non-XPLINK application calling the XPLINK parser will not see the performance benefit shown here. In this case, calls within the XPLINK parser will be more efficient, but calls from the application to/from the parser will be less efficient. These calls occur during processing of SAX events and traversal of parsed DOM trees in order to examine or retrieve data. As frequent communication between the parser and the application is generally required, most non-XPLINK applications will perform better when the non-XPLINK version of the parser is used.
