On a database with 180 million records, 150 million of which are compressable: Compressed Compress Uncompress Size % of time time uncompressed microseconds microseconds ------------------------------------------------------- zlib 38 96 12.5 lz4 52 7.4 1.6 ------------------------------------------------------- lz4 is an order of magnitude faster than zlib, however, lz4-compressed records were 36% larger. For me, I don't think the speedup is worth the loss of compression.
