Diagnosis
The CPU statistics are important in order to maintain a smooth systemperformance. In this case, too many processes are waiting to beprocessed by the CPU.

System Response
System performance is restricted.

Procedure
For detailed information about the CPU load, select the node and choose"Start Analysis Method". Check the following performance factors:

• Which processes are causing the load?


• Check if all other processes with high CPU loads (memlog,

r3trans, nwengine, brbackup...) are necessary.

• If high values are displayed for the CPUtime, the process could be in a
loop.

• The resident size of a SAP work process should, depending on the size of
the ztta/roll_area, be around 9#12 MB.
You can also display SAP work processes with a high CPU load using theprocess overview (Transaktion SM50). The SAP process overview displaysthe ABAP program that is using the CPU.
