Members

ConnectCount

Tracks the number of times that Connect was called.

ConnectSum

Tracks the number of ticks of the high-performance counter that have been spent in Connect calls for the socket.

DisconnectCount

Tracks the number of times that Disconnect was called.

DisconnectSum

Tracks the number of ticks of the high-performance counter that have been spent in Disconnect calls for the socket.

SendCount

Tracks the number of times that Send was called.

SendSum

Tracks the number of ticks of the high-performance counter that have been spent in Send calls for the socket.

ReceiveCount

Tracks the number of times that Receive was called.

ReceiveSum

Tracks the number of ticks of the high-performance counter that have been spent in Receive calls for the socket.

ReleaseCount

Tracks the number of times that Release was called.

ReleaseSum

Tracks the number of ticks of the high-performance counter that have been spent in Release calls for the socket.

ControlSocketCount

Tracks the number of times that ControlSocket was called.

ControlSocketSum

Tracks the number of ticks of the high-performance counter that have been spent in ControlSocket calls for the socket.

Remarks

Http.sys can provide statistics on the time spent on specific API calls as listed here. Since the gathering of statistics has a slight overhead in time and memory, there's a registry key that you'll need to set in order to enable using HTTP_WSK_API_TIMINGS. For more details, see the notes in HTTP_REQUEST_PROPERTY.

To check the actual duration of an HPC tick, see QueryPerformanceFrequency.
