RozoFS is no longer developped (last commit was july last year). It would be nice to have an alternative implementation of the same algorithm, well maintained. It's sad to see Free Software being frozen. But Free Software is never dead, all it needs is good will and a little work to be resurected ! I've never seen any benchmark regarding performances, that would be the first step.
