SAP_CCMS_MONI_BATCH_DP takes along time to complete

SAP_CCMS_MONI_BATCH_DP is taking a long time to complete on CRM 4.0 installed on windows 2003 server.

It does it randomly and that results in the slow performance of the System.

Unable to find the reason why it takes longtime to complete and how can i avoid that to happen.

Thanks and regards,
