Different data set + Interesting results summary

I've tried it on 6.1MB plain text files on a dual-core machine. tar -cf zzz.tar * && bzip2 -9 zzz.tar took 1.5s and resulted in a 968k file, while the same with xz using your options took 11s and resulted in an 863k file. So xz took 7 times as long while offering about 11% better compression with that input. My conclusion: if in a frequent process I want to (temporarily) save some space, I'd rather go with bzip2 – while for long-time archival, xz might be the better choice. Though this conclusion is based on too little data :)
