Summary

For best performance - the Machine Pool Page fault rate should remain below 10/sec.

Objective

For best performance the maximum page faults per second for the machine pool should remain below 10/sec.   Many operating system functions run in the machine pool and excessive page faults in the machine pool can lead to system wide performance impact.  

Please note: This recommendation is a general guideline due to the wide variety of system roles and applications that now run on IBM i.   IBM does not publish page fault guidelines for other memory pools.
