Precision Timer Algorithm Counter Types
The precision timer algorithm counter types obtain more accurate readings than system timers. The service that provides the data also provides a timestamp, which eliminates the errors that can occur because of the small and variable time that elapses between capture of the system timestamp and collection of the data from the performance DLL. This base timestamp for precision timers is a PERF_PRECISION_TIMESTAMP property, which must immediately follow the PERF_PRECISION_TIMER property.
|Similar to PERF_COUNTER_TIMER except that it uses a counter defined time base instead of the system timestamp.|
|Similar to PERF_100NSEC_TIMER except that it uses a 100ns counter defined time base instead of the system 100ns timestamp.|
