Hi,
During the past week I decided to use native decompress for a Hadoop job
(using 0.20.0). But before implementing it I decided to write a small
benchmark just so understand how much faster (better) it was. The result
came out as a surprise

Jens,
As your test shows, using a native codec won't make much sense for
small files, since the involved JNI overhead will likely out-weight
any possible gains. With all the performance improvements in java 5 +
6 its reasonable to ask whether the native implementation does really
improve
