Mint Media Interactive created CXF-8571:
-------------------------------------------
Summary: Enum serialization slowed down by the search for
XmlEnumValue annotation.
Key: CXF-8571
URL: https://issues.apache.org/jira/browse/CXF-8571
Project: CXF
Issue Type: Bug
Components: Aegis Databinding
Affects Versions: 3.3.5
Reporter: Mint Media Interactive
Attachments: EnumType.java.diff, EnumType.mod.java, callTree.png
Using CXF for SOAP serialization we noticed a significant performance issue
with intensive CPU load when the serialization of enum values is involved: it
appeared to us that most time is spent in
org.apache.cxf.aegis.type.java5.EnumType while the annotation belonging to the
given enum is searched.
!callTree.png!
The sought annotation is XmlEnumValue, used to specify a custom string to
serialize a member of the enumeration, in place of its simple name. Our code
does not make use of that annotation: so we got a notable performance
improvement (about 20%-30% in some calls) just by modifying the EnumType class
in order to not look for it.
[^EnumType.mod.java] [^EnumType.java.diff]
We think it might be useful to have an option or setting to disable searching
for that annotation or to activate some other comparable optimization.
