So I took a look and my feedback: You have a blurb about how to use the parallel code in commons-compress but there is no test or example that actually shows how to make one. The actual working example is in plexus-archiver and if you don't mind I'd like to put a utility in commons-compress so that users can easily utilize the code. Basically "use this number of threads and you go make it faster". Something like the ConcurrentJarCreator but general purpose, and that utility can probably be used, with instruction from the user, to do the work in parallel. It would be really nice just to weave the code into the existing code paths so users just get the benefit with an upgrade.
