Thanks, and today I used another machine to test zswap.
The total ram size of that machine is around 4G.
This time the result is better:
rc6 rc6
zswap base

But the performance of the first machine I used whose total ram size
is 2G is still bad.
I need more time to summarize those testing results.
Maybe you can also have a try with lower total ram size.
