performance comparison code
Environment:
Ubuntu Linux/amd64
x86 jre 1.5.0_13-b05
ant.jar in ant-1.7.1
I'd like to use org.apache.tools.zip instead of java.util.zip because of the
filename encoding problem of java.util.zip, and have a performance problem on
org.apache.tools.zip.
The attached Java code compress 2 files (3MiB and 2MiB) with org.apache.zip and
java.util.zip. It shows org.apche.zip is 20x slower than java.util.zip.
