LZMA2算法是一种基于LZ77算法的压缩算法,它使用字典匹配和动态编码来实现高效的压缩。在压缩数据时,LZMA2算法将输入数据分割成多个块,然后对每个块进行压缩。在解压数据时,它使用相同的字典来重建原始数据。 2. 快速压缩算法 快速压缩算法(Fast-LZMA2)是对LZMA2算法的简化和优化。它通过减少内存使用和优化编码过程来...
在这张表中,另外一个非常亮眼的,就是LZMA家族在如此高效率区间下,唯一存活的一种算法,同时也是LZMA家族当中最新版本fastLZMA2,因为吸收了zstd的一些先进经验,在压缩比减少不多的情况下,获得了能够和RAR相提并论的效率,特别是fastLZMA2压缩级别在五以下的时候,不仅压缩率高于RAR,而且效率还高于RAR的级别二,可以说,...

lzbench is an in-memory benchmark of open-source LZ77/LZSS/LZMA compressors - added fast-lzma2 1.0.1 · warpspeed-world/lzbench@7c1aa27
Fast LZMA2v1.0.1 is a LZMA2 compression algorithm, 20% to 100% faster than normal LZMA2 at levels 5 and above, but with a slightly lower compression ratio. It uses a parallel buffered radix matchfinder and some optimizations from Zstandard. The codec uses much less additional memory per ...
