Web11 de ago. de 2024 · It's a good question, but it seems, answer is simple: the unpacker should ONLY copy literals from compressed data, and copy some bytes from already uncompressed data. If an optimized unpacker uncompresses enwik8 more than 0.5 sec. on 1 core, then it's not pure LZ77 compression. In packed enwik8 at the beginning of the …
