deckrider updated COMPRESS-82:
------------------------------

    Attachment: cpio-speed-patch.txt

It seems that the attached patch fixes the speed issue.

I'm not familiar with java.io that much.  I thought just switching to 
java.io.BufferedOutputStream would be sufficient, but I had to use flush() or 
it broke things.

Hopefully someone more experienced can translate this patch to a more correct 
way of handling the issue.

> I have a directory with 20 jar files in it to be placed into a cpio archive.  
> This seems VERY slow (about 3 minutes).  It is almost immediate with the 
> linux cpio command (of course its non-java).  is there any way to improve 
> speed for the cpio archiving?
