LRZIP - a new up and coming compression?

Long Range ZIP / Lzma RZIP

It seems to combine the best parts of various algorithms for large files. One big downfall is the amount of memory it needs to create the highly compressed archives, but it is needed to be able to get the results it gets.

Very interesting to keep an eye on development though and very handy if you are running tight on disk space and not on RAM. Thankfully you don't need much ram to uncompress the archives.

You can check out the website here.

A good example from the README file:

Uncompressed: 616.99 MB
gzip: 207.97 MB
bzip2 -9: 183.57 MB
lzma -9: 93.18 MB
lrzip -M: 78.88 MB

Impressive.

And it is fast!
Often faster than bzip2 or lzma alone.

A more interesting example:

Uncompressed tar file with AVI files: 3206 GB
gzip -9: 3179 GB
bzip2 -9: 3178 GB
xz -9: 3175 GB
7z: 3180 GB
lrzip -M: 2829 GB
lrzip -l: 2840 GB

The times were over 45 min. for bzip2, xz and 7z.
The time was 22 min. for lrzip -M.
The time was less than 5 min. for lrzip -l.
