- - switched to GPL v2 or any later version.
+ - switched to 2-clause bsd with "GPL v2 or any later version" option.
- speed up compression by ~10-15% in common cases
by some manual unrolling.
- - import some compiler tricks from JSON::XS.
+ - import some compiler tricks from JSON::XS, for further speed-ups.
- tune hash functions depending on ULTRA_FAST or VERY_FAST settings.
- for typical binary data (e.g. /bin/bash, memory dumps,
canterbury corpus etc.), speed is now comparable to fastlz, but
with better compression ratio. with ULTRA_FAST, it's typically
3-15% faster than fastlz while still maintaining a similar ratio.
(amd64 and core 2 duo, ymmv). thanks a lot for the competition :)
- - undo inline assembly, it is no longer helpful.
+ - undo inline assembly in compressor, it is no longer helpful.
- no changes to the decompressor.
- use a HLOG of 16 by default now (formerly 15).
