Find Archive job (delete action) overrun a low in production

Hi All,

We are now running Contact log archiving in our production. And recently, we find that the ARV_ISU_BCONT_DEL* overrun a lot. e.g. it takes about 200 second to delete 10000 archived record. But it found that it run around 35,000 second to delete around 4500 archived record. I capture the statistics for deleted data object. it looks odd that the statistic show SRL_ARLNK of 4500 archived job with 275334 records. it is much highed than normal run figure. Do you have any idea?
