In case some of you are interested, it is said to achieve 15% better compression rates than bzip2 while being 2 to 5 times faster. And decompression is nearly as fast as gunzip (see http://tukaani.org/lzma/).
[AUR] lzma 4.32.0beta2-3 [unsupported] Compression program, stronger and slower than bzip2
[AUR] lzma-utils 4.32.5-1 [community] Compression utility like bzip2, but 15% better and 2-5 times faster
This is odd :)
I did a quick test, and lzma -1 seems to achieve a similar compression ratio than bzip2, in less time : 8s vs 10s. That's not exactly a 2-5 times faster. It was also faster at decompressing, 2s vs 3s. So it does seem like it should be preferred to bzip2, but it's still not comparable to gzip, which has a lower compression rate but is much faster at both compression and decompression.
