LZAV – Fast In-Memory Data Compression Algorithm (In C)
What do you mean &quot;in-memory&quot;? Is there any other kind of data compression algorithm?<p>How does it compare with zstd? I find that zstd, given the right compression level, can beat almost every other compression algorithm nowadays on at least one or two metrics, and very often on all metrics.<p>For example, I just tried to compress the `enwik9` dataset with both lz4 and `zstd -1 --single-thread` and zstd was both faster on compression and decompression and also produced a 357 MB file compared to 509 MB with lz4. According to these results, apparently it would beat LZAV on every metric?<p>That said, even though I used `--single-thread`, somehow zstd still used 150% of CPU according to `time` (?).
