3.7.3 Performance of the Parser Switching functionality
When you do not use the Parser Switching functionality, the processing has the same performance as in the case of version 09-00.
If the Parser Switching functionality is used, the processing speed reduces by a few milliseconds the first time when the Factory class instances described in 3.7.1(2) Types of the target XML implementations are generated. From the second and subsequent times, the deterioration is not problematic. There is no performance deterioration for the javax.xml.validation.SchemaFactory, javax.xml.xpath.XPathFactory, and javax.xml.bind.JAXBContext APIs.
