This time we will focus on the startup time. The process start time is important if your processes are not persistent. If you are using FastCGI, mod_perl, mod_php, or mod_python, then these statistics are not so important to you. However, if you are spawning many processes which do something small and live for a very short time, then you should consider the CPU resources which get wasted while the script interpreter is being initialized.

The benchmarked scripts do only one thing – say “Hello, world” on the standard output. They do not include any additional modules in their source code – this may, or may not be your use-case. Though, very often the scripting languages have pretty many built-in functions, and for simple tasks you never need to include other modules.

Here are the benchmark results:

The clear winner among the script languages this time is… Perl.

All scripts were invoked 3000 times using the following Bash loop:

time ( i=3000 ; while [ "$i" -gt 0 ]; do $CMD >/dev/null ; i=$(($i-1)); done )

All tests were done on a Kubuntu Lucid box. The versions of the used software packages follow:

• g++ (GNU project C and C++ compiler) 4.4.3
• Python 2.6.5
• Python Psyco 1.6 (1ubuntu2)
• Perl 5.10.1
• PHP 5.3.2 (1ubuntu4.2 with Suhosin-Patch), Zend Engine 2.3.0

The C++ implementation follows, click “show source” below to see the full source:

#include <iostream>
using namespace std;

int main() {
	cout << "Hello, world!\n";
	return 0;
}

The Perl implementation follows, click “show source” below to see the full source:

use strict;
use warnings;

print "Hello, world!\n";

The PHP implementation follows, click “show source” below to see the full source:

<?php
echo "Hello, world!\n";

The Python implementation follows, click “show source” below to see the full source:

#import psyco
#psyco.full()

print 'Hello, world!'

Update (Jan/14/2012): Copied the used test environment info here.

Update: There is a part #2 of the benchmark results.

This all began as a colleague of mine stated that Python was so damn slow for maths. Which really astonished me and made me check it out, as my father told me once that he was very satisfied with Python, as it was very maths oriented.

The benchmarks here do not try to be complete, as they are showing the performance of the languages in one aspect, and mainly: loops, arrays with numbers, basic math operations.

Note: Give your ideas and use-cases on what to benchmark, and I’ll try to implement it for you. I.e. “benchmark the languages for reading a file, then splitting it to tokens by white-space and finally outputting all unique elements and their count”.

Out of curiosity, Python was also benchmarked with and without the Psyco Python extension, which people say could greatly speed up the execution of any Python code without any modifications.

Here are the benchmark results:

The clear winner among the script languages is… Python.

NodeJS JavaScript is pretty fast too, but internally it works more like a compiled language. See the comments below.

The times include the interpretation/parsing phase for each language, but it’s so small that its significance is negligible. The math function is called 10 times, in order to have more reliable results. All scripts are using the very same algorithm to calculate the prime numbers in a given range. The correctness of the implementation is not so important, as we just want to check how fast the languages perform. The original Python algorithm was taken from http://www.daniweb.com/code/snippet216871.html.

The tests were run on an Ubuntu Linux machine.

Update (Jul/24/2010): Added the C++ optimized values.
Update (Aug/02/2010): Added a link to the benchmarks, part #2.
Update (Mar/31/2011): Using range() in PHP improves performance with 5%.
Update (Jan/14/2012): Re-organized the results summary table and the page. Added Java.
