Hi Mr. Yap, Thank you for your performance improvement report. This performance problem is truly extremely minor. Besides, it is also well analysed and solutions are proposed in the WorkLog entry that you mention. Also, we do not feel a need to introduce yet another flag, when this operation can be optimised with very few existing parameters. However, this improvement needs to be scheduled for some version in the future, which is why we will verify this report. Also, performance improvements are introduced only in the latest GA versions or in the development versions only. This is reflected in the target version above. Verified as reported.
