[jira] [Commented] (AXIS2-5119) ComplexType array return performance issue

["Vilnis Termanis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AXIS2-5119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13083470#comment-13083470 ] 

Vilnis Termanis commented on AXIS2-5119:
----------------------------------------

Comments regarding potential solution (attached BeanUtil.java):

- Before/after performance when return is a 10k custom object array: ~15.2s / 3.5s (!!)
- Caching should maybe happen higher up, e.g in getPullParser() or getPropertyQnameList()
- Addition of axis2 service parameter to enable/disable such caching
- Is this the right approach at all to improve performance?

>          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

> 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.)
