$TimeUnit

$TimeUnit
gives the minimum time interval in seconds recorded on your computer system.
  • Typical values for $TimeUnit are 1/100 and 1/1000.
  • In some functions the actual time granularity may be much smaller than $TimeUnit.
The timing granularity on this machine:
When a computation takes less than $TimeUnit seconds, repeat to get a better timing:
Divide by the number of repetitions to get the average timing:
You may want to time just a part of the computation:
