|
Unix's `time` utility is a simple and often effective way of measuring
|
|
how long a command takes to run. Unfortunately, running a command once
|
|
can give misleading timings: the process may create a cache on its first
|
|
execution, running faster subsequently; other processes may cause the
|
|
command to be starved of CPU or IO time; etc. It is common to see people
|
|
run `time` several times and take whichever values they feel most
|
|
comfortable with. Inevitably, this causes problems.
|
|
|
|
`multitime` is, in essence, a simple extension to time which runs a
|
|
command multiple times and prints the timing means (with confidence
|
|
intervals), standard deviations, minimums, medians, and maximums having
|
|
done so. This can give a much better understanding of the command's
|
|
performance.
