    Description

      Measurements are showing some tuning is needed in buffer sizes for the binary compressed serialization/deserialization code. Reducing one buffer from a max of 32k to 1k showed a speed up in deserialization of more than 2.5 x using an IBM JVM on an Intil i7 with 128K L1; using a Oracle JVM - there was a minor speedup. This effect appears to be due to L1 cache flushing/dumping.

      Check and tune both form 4 and 6.
