Hello Zhou,
The performance improvement shows great according to your data. However,
the data is not that enough to show the change of common use.
Since the amount of 0/1 in a page will cause the vary of time used for
compression, I would like you get more benchmark on different core with
different amount of 0/1.

Hello Kumagai,
I test it, and it works well. The following is the results.
in virtual machine(memory 2G):
with empty memory:

full memory means memory is occupied by 1, without 0?
