Page Faults and the Inetinfo Working Set

When you look at page faults, compare your data on the size of the Inetinfo working set to the rate of page faults attributed to the working set. As Table 5.1 showed, you can use the Computername\ Process\ Working Set: Inetinfo counter as an indicator of the size of the working set, and the Computername\ Process\ Page Faults/sec: Inetinfo counter to indicate the rate of page faults for the IIS 5.0 process. When you have reviewed data on the varying size of the Inetinfo working set, you can use its page fault rate to determine whether the system has enough memory to operate efficiently. If the system is not able to lower the page fault rate to an acceptable level, you should add memory to improve performance.
