How Do You Rapidly Benchmark Scripts

I've seen a lot of blogs where authors discuss throwing together quick benchmark tests, like this Ruby 1.9.0 v Python 2.5.1 that Antonio Cangiano "throws together at 3am."

Is there a simple way to time a script to the millisecond like that that I'm unaware of? Is he probably using built-in functions of OS X or individual libraries? Does Python have a standard lib for this?

How would you do this if you were just going to take the path of least resistance and throw it together at 3am?

for ruby benchmarking try this

require 'benchmark'

Benchmark.realtime do #your code,this end

also try measure which give more detail total system time etc

Benchmark.measure do

Ruby has a Benchmark module as part of the standard distribution. It's simple to use. A quick search here on Stack Overflow will turn up a lot of samples of its use that I've done.

If you're after mere benchmarking, and you're not too worried about start-up time, and you want it to be programming language independent and you're on Unix, you'd probably use unix time:

time ruby -e "1.upto(10000000) {|i| i}"
real    0m2.926s
user    0m1.570s
sys 0m1.350s

I don't know how to do this in Ruby, but in Python I do this -

import time
def my_function():
    a = time.clock()
    //code which you want to benchmark
    b = time.clock()
    print b-a

Obviously, this is a "throw together at 3am benchmark." No frills.

Take a look at the timeit module.
