Buffer waits on partition table

Hi all,

   My DBA partition table two weeks ago. The partitioning is ok, I review statspack (we use 9.2.0.4) and see at the "Top 5 Buf. Busy Waits per Segment for DB", I can see Buffer Busy Waits of these partitions are high, they look like:

                                                                                                                                                          Buffer
                                                                                                            Subobject             Obj.           Busy
Owner               Tablespace           Object Name                        Name                    Type           Waits        %Total
----------              ----------                   --------------------                      ----------                  -----             ------------   -------
ACEVNPRD2   LIFEDATA_T_1     T_CUST_DEPOSIT_LIST     T_01012010      TABLE        8,479        23.26
ACEVNPRD2   LIFEDATA_T_2     T_CUST_DEPOSIT_LIST     T_31122010      TABLE        5,081       13.94
ACEVNPRD2   LIFEDATA_T _1    T_CUST_DEPOSIT_LIST     T_31122011      TABLE        3,350        9.19
ACEVNPRD2   LIFEDATA_T _3    T_CUST_DEPOSIT_LIST     T_30062011      TABLE        3,113        8.54
ACEVNPRD2   LIFEDATA_T _2    T_CUST_DEPOSIT_LIST     T_30062012      TABLE        2,554        7.01

Howdy, Stranger!
