Enqueue Locks -batch job processing

Hi Experts,

We have upgraded our SAP ECC environment from 6.0 ehp4 to ECC 6.0 ehp7. Before upgrade XXX job was running with 4000 seconds, but post upgrade the same job is running long with 20000 to 25000 seconds.
During the job run, we are getting 900+ exclusive lock entries.

Does this issue related to the SAP Note given below, we are on 740 Kernel release and we are having integrated enqueue WP(not a separate one)
2013043 - Performance Problems with Enqueue Work Process

or should we try some other solution before splitting Enqueue WP from the integrated environment?

Thanks,

Preetha Balan
