[jira] Created: (AXIS2-4524) Caching BeanInfo in adb module's
BeanUtil improves performance
Caching BeanInfo in adb module's BeanUtil improves performance
--------------------------------------------------------------
Key: AXIS2-4524
URL: https://issues.apache.org/jira/browse/AXIS2-4524
Project: Axis 2.0 (Axis2)
Issue Type: Improvement
Components: adb
Affects Versions: 1.5
Reporter: Valgeir Halldórsson
I've detected that org.apache.axis2.databinding.utils.BeanUtil class can be improved for performance. It seems that invoking Introspector.getBeanInfo(Class, Class) takes a lot of time. By caching java.beans.BeanInfo in this class it doubles up (at least) the performance, especially when returning a big dataset. I changed this myself and saw a great deal of performance improvement.
