If with Transaction ST06 or on the CCMS Alert Monitor you notice a high paging rate in a memory pool, enlarge this pool. The paging rate should be less than 10 faults per second. The following example can help you when assessing paging rates in your system:
Faults in the memory pool used by R/3 | 200 faults per second |
Number of active work processes (not the total number of work processes) | 10 |
Average number of faults per work process | 20 faults per second |
Paging overhead (assumed average response time of the hard disks is 10 millisec.) | 200 millisec. per second |
This corresponds to a paging overhead of 20%. Do not exceed the 20% limit.
