- Bugzilla Bug (s) Resolved:
[132776] Performance: runing RunAndRender Task with the attached report have
regression
- Description:
The bug is introduced during our adoption of ibm ICU to BIRT project. In class
DataTypeUtil we use method com.ibm.icu.text.DateFormat.getDateInstance() and
com.ibm.icu.text.DateFormat.getDateTimeInstance(). These two method, however, is
10 times slower than their counterpart in java standard library, that is, java.text.DateFormat.getDateInstance()
and java.text.DateFormat.getDateTimeInstance(). This is the source of this bug.
We change the
algorithm in class DataTypeUtil so that reduce the use of these two method in
ICU.The bug is fixed.
