    Description

      5u6 is faster than 5u10 if we compare the performance of the GZIPInputStream.

      $ java -DLOOPS=1000 -showversion CpuPerformanceInflateBytes
      java version "1.5.0_06"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
      Java HotSpot(TM) Server VM (build 1.5.0_06-b05, mixed mode)

      time: 17982
