Bzip Outperforms LZ77 Compressors On Code

On March 12, 2026 a Reddit post analyzes compressing a 327 KB Lua codebase from the Minecraft ComputerCraft mod and finds bzip-family compressors (bzip2, bzip3) yield the best ratios, reducing the file to roughly 61–64 KB versus 67–76 KB for zstd, xz, gzip, brotli, and lzip. The author attributes gains to the Burrows–Wheeler Transform’s context grouping and argues this enables much smaller, simpler decoders for self-extracting Lua archives.
Scoring Rationale
Measured compression gains and decoder-size analysis justify usefulness, but credibility limited by a single Reddit post and informal evaluation.
