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.
