Also, a new project that compares performance & efficiency
(time/space) of JVM-accessible compression codecs is at:

https://github.com/ning/jvm-compressor-benchmark

and although default does not yet compare differences between deflate
levels would be easy to modify to also do that. Currently it does
include 2 deflate codecs, bzip2, quicklz, lzf and snappy (via JNI).

ps. It would be really nice to have benchmarks for "big data" use
cases for codecs -- jvm-serialization-benchmark for example just deals
with individual small messages. But there are multiple applicable data
formats, with very little good detailed comparative performance
benchmarking. :-/
