staticprivate

Here is the caller graph for this function:

FrameStart()

Table<size_t>& Stats::FrameStart ( )

inline

Dimensions = number of packet RX threads x kNumStatsFrames. frame_start[i][j] is the RDTSC timestamp taken by thread i when it starts receiving frame j.

GetDurationStat()

DurationStat* Stats::GetDurationStat ( DoerType  doer_type, size_t  thread_id  )

inline

Get the DurationStat object used by thread thread_id for DoerType doer_type

Here is the call graph for this function:

Here is the caller graph for this function:

GetDurationStatOld()

DurationStat* Stats::GetDurationStatOld ( DoerType  doer_type, size_t  thread_id  )

inline

The master thread uses a stale copy of DurationStats to compute differences. This gets the DurationStat object for thread thread_id for DoerType doer_type.
