LZ4 - Extremely Fast Compression Algorithm

Postby jomcty » 18 Jul 2013, 22:30

Can we get LZ4, a very fast lossless compression algorithm, included in the next build sysrcd?

Thanks!

Scratch that. My testing revealed that LZ4 currently isn't any faster than LZOP and the multi-core support is only on the Windows port at the moment.

There is a multi-threaded version here:
https://github.com/t-mat/lz4mt

Please consider it.
Note: I have not tested/used it at all. Will report when I do, if desired.

Rationale: Atom CPUs a are really really slow, but many have more than one core.

lz4 seems included now (at least it is listed on http://www.sysresccd.org/Detailed-packages-list )

http://www.blosc.org/ seems like an interesting alternative (supports multi-threading).
