Hi Mario, This is common knowledge but not completely true. The bottleneck of BWT is the suffix sorting step and there have been many recent advances that significantly reduced the time and space needs of the algorithm. Of course, it will probably never be so fast as a lightweight Ziv-Lempel imple

n the subject; 2) lzo is copyrighted, so it's not clear if it can be used on ZFS; 3) lzo is just another implementation of Ziv-Lempel while BWT is a completely different approach. Why not try it? Domingos. -- Domingos Soares Neto University of Sao Paulo Institute of Mathematics and Statistics
