Thanks Art Kagel ...
The following is what I get in the server :
>- How many LRUs do you have configured?
LRUS 8
LRU_MAX_DIRTY 2
LRU_MIN_DIRTY 1
>- How much cache is configured?
Sorry..I don't know what this means ... Buffers ?!
Physical Log Buffer Size [ 128] K
Logical Log Buffer Size [ 128] K
Max # of Logical Logs [ 200]
Max # of Locks [ 2000000]
Max # of Buffers [ 100000]

I noticed that chuck 2 contained all the tables since chunk 3,4,5 are empty,
so I just create those busy tables to chunk 3,4,5 will make I/o more smooth,
I think ~~~
