Members

cb

The size of the structure, in bytes.

PageFaultCount

The number of page faults.

PeakWorkingSetSize

The peak working set size, in bytes.

WorkingSetSize

The current working set size, in bytes

QuotaPeakPagedPoolUsage

The peak paged pool usage, in bytes.

QuotaPagedPoolUsage

The current paged pool usage, in bytes.

QuotaPeakNonPagedPoolUsage

The peak non-paged pool usage, in bytes.

QuotaNonPagedPoolUsage

The current non-paged pool usage, in bytes.

PagefileUsage

The Commit Charge value in bytes for this process. Commit Charge is the total amount of private memory that the memory manager has committed for a running process.

PeakPagefileUsage

The peak value in bytes of the Commit Charge during the lifetime of this process.

PrivateUsage

Same as PagefileUsage. The Commit Charge value in bytes for this process. Commit Charge is the total amount of private memory that the memory manager has committed for a running process.

PrivateWorkingSetSize

The current private working set size, in bytes.

SharedCommitUsage

The current shared commit usage, in bytes.
