>             Project: Harmony
>          Issue Type: Improvement
>          Components: Classlib
>    Affects Versions: 5.0M6
>         Environment: Pack200 HEAD

> I found one more opportunity for buffering to improve the speed of the pack200 Archive
API by about 8% when unpacking  from one file to another.
> This won't affect the performance of the Pack200.Unpacker API, but will serve as a useful
example of why it's important to pass a buffered JarOutputStream in rather than a simple JarOutputStream
on a FileOutputStream.
