Description

In the file

./axis2-1.5.4/modules/tool/axis2-idea-plugin/src/main/java/org/apache/axis2/tools/wizardframe/WizardFrame.java line:323

The buffer size is fixed at 1024 bytes.

To copy 10M data with 1024-byte buffer it takes 338,591,180 nano-second, while it takes 105,384,689 nano-second with a 10240-byte buffer.
