Stefan, you are right.
I have updated BZip of course, not Zip. It's quite hard with all these patches around me currently :-)

> This has been reported against Ant's version, the grandfather of commons-compress. See https://issues.apache.org/bugzilla/show_bug.cgi?id=45396
> Splitting up the array passed into Deflater.setInput improves the performance dramatically. Ant's change is http://svn.apache.org/viewvc/ant/core/trunk/src/main/org/apache/tools/zip/ZipOutputStream.java?r1=579278&r2=677272&pathrev=677272
