Subject [jira] [Created] (AXIS2-5119) ComplexType array return performance issue
Date Thu, 11 Aug 2011 20:12:29 GMT
ComplexType array return performance issue
------------------------------------------

                 Key: AXIS2-5119
                 URL: https://issues.apache.org/jira/browse/AXIS2-5119
             Project: Axis2
          Issue Type: Improvement
          Components: adb
    Affects Versions: 1.6.0
         Environment: Ubuntu 10.04 64-bit, Tomcat 6.0.28, Axis 1.6.0
            Reporter: Vilnis Termanis
         Attachments: BeanUtil.java

Service function returns which contain (long) arrays of custom objects degrade performance.

Example (POJO):
SomeCustomType[] myFunc() is a lot slower than String[] myFunc()

Reason:
BeanUtil.getBeanInfo() (modules/adb/src/org/apache/axis2/databinding/utils/BeanUtil.java)
is called for each element in the output array, even though they are all the same. (According
to http://download.oracle.com/javase/6/docs/api/java/beans/BeanInfo.html the result should
be cached but this does not seem to be happening.)
