anybody lrzip??

[CodeMutant]

has any one tried lrzip? i have been using it for the last few days... seems "good"....can anyone tell if its "impressive"??.. in its code, i read a few many optimisations for large sized files..... but wont a "block" mode of normal tools like zip and 7z do the same..
is lrzip "preprocessing" more efficient??

anybody have any take on that?

using "lrzip -n" on tarfile and then 7z with level 9, i got 10mb improvement than just plain 7z on the source directory(no tar file created)...

The source i took was 2.5gb ubuntu "/" backup.

plain 7z : 704.5mb
.tar.lrz.7z : 693.1mb

Some time ago Bulat done a few experiments an wrote his own preprocessor for such needs... In other words the idea is not new, and successfully used!
