It's faster; a lot faster - and it scales beautifully. But then again you probably need "war/ear/zip" heavy builds to really get max effect. The average "jar" plugin does not usually consume that large a percentage the average build.
I'll try to make some nice graphs and a blog post some time this weekend. It's a new api in commons-compress, the existing api did translate well to multithreading. You can look at plexus-archiver changes if you want to see how it's used. I've also written some docs in commons-compress itself.
