| microtiming_precision {microbenchmark} | R Documentation |
This function is currently experimental. Its main use is
to judge the quality of the underlying timer
implementation of the operating system. The function
measures the overhead of timing a C function call
rounds times and returns all non-zero timings
observed. This can be used to judge the granularity and
resolution of the timing subsystem.
