I've put a port for sysutils/multitime into openbsd-wip [1]. From the DESCR:
Unix's 'time' utility is a simple and often effective way of measuring how
long a command takes to run ('wall time'). 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, standard deviations, mins,
medians, and maxes having done so. This can give a much better understanding
of the command's performance.
As well its more advanced features, multitime also has the advantage that it
can be used as a drop-in replacement for /usr/bin/time. More at
<http://tratt.net/laurie/src/multitime/>.
This was developed on OpenBSD and has been heavily tested on amd64. Reports
from other architectures, and general comments and questions are welcome!
