Functions in system modules, Run Time tab, settings Dialog Boxes

Select the timing method to use to record time for functions in system modules (certain modules located in the Windows directories and which Quantify always times; for example, Ntdll.dll).

You can choose from the following methods:

Elapsed time

The total elapsed (wall-clock) time required for an operation. This includes time spent waiting for I/O, synchronization objects, timers, scheduling, and other delays.

Kernel time

The amount of time the thread spends in kernel mode.

User + Kernel time

The amount of time executing code in the thread. It does not include time spent waiting for devices or servicing other processes.

User time

The amount of time the thread spends executing code in user mode.

Ignore

Quantify records the time as zero (0).

Note:

§      The Time measurement type is not supported for selective instrumentation.
