Marshall Schor resolved UIMA-4283.
----------------------------------
Resolution: Fixed
Assignee: Marshall Schor
the compress part already had reduced buffer sizes, so the only change made was
to reduce the 32k zip buffer for decompression to 1k for both form 4 and 6

> 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.
