Relative ratios according to http://catchchallenger.first-world.info//wiki/Quick_Benchmark:_Gzip_vs_Bzip2_vs_LZMA_vs_XZ_vs_LZ4_vs_LZO Compressed size gzip (1) - lzo (1.4) - lz4 (1.4) Compression Time gzip (5) - lzo (1) - lz4 (0.8) Decompression Time gzip (9) - lzo (4) - lz4 (1) Compression Memory gzip (1) - lzo (2) - lz4 (20) Decompression Memory gzip (1) - lzo (2) - lz4 (130). Yes 130! not a typo. But there is a note: Note: lz4 it's the program using this size, the code for internal lz4 use very less memory. However, I could not find any better apples to apples comparison. If lz4's real memory consumption is in orders of lzo, than it looks good. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
