This document discusses a performance test comparing the initialization time of JAX-WS according to the size of WSDL and XSD files. The test found that the larger the size of the WSDL and XSD files, the more time spent on initialization. However, after initialization, the performance was similar regardless of the number of VO files due to caching of the JAXB context. The test was conducted on a Lenovo laptop using WebSphere Application Server v8.5.5 and Apache JMeter to invoke a simple JAX-WS web service application with variable arguments.
