This is a small util I wrote in D which is like the unix
'time' command but can repeat the command N times and show
median, average, standard deviation, minimum and maximum.

As you all know, it is not proper to conclude that
a program is faster than another program by running
them just once.

It's BOOST and is in github:

https://github.com/jmcabo/avgtime

Example:

avgtime -r 10 -q ls -lR /etc

------------------------
Total time (ms): 933.742
Repetitions : 10
Median time : 90.505
Avg time : 93.3742
Std dev. : 4.66808
Minimum : 88.732
Maximum : 101.225

The -q argument pipes stderr and stdout of the program
under test to /dev/null

I put more info in the github page.

HAVE FUN!!

It'd be neat if it could create comparison statistics between the execution of two different programs so you could compare the performance of changes or alternative approaches to the same problem as I was doing.
