Street Fight: PHP vs Java (Part 1)

Please welcome our newest regular GJ blogger: The Blackdood

Ooooo! fight! fight! fight!.

This is a fight that has been going on for as long as I can remember. Some say Java is too heavy, some say PHP is too light. I'm here to tell you how it is.

To be fair, I was first a Perl programmer, and that didn't last long. I then moved to PHP3. I was a PHP developer up until about a year ago, straight through PHP5. Now, I develop for both. I have managed teams of both PHP developers and Java developers, and developed large scale applications in both.

PHP has come a long way since the days of version 3. The new object model is a step in the right direction, and OO programming is no longer as big of a performance hog. As a result, a ton of PHP frameworks have started popping up. The one I've used the most is Symfony ( http://www.symfony-project.com), it's basically a port of RoR. The Java framework I am using is WebWork ( http://www.opensymphony.com/webwork/).

This is the first article of many to come. This first one will cover VERY basic performance results, and we'll get more detailed as time goes on and users request. What I will be focusing on is ACTUAL development with, not the actual benchmark results

Now, let's get the numbers out of the way. I did some minor benchmarking, but we all know that benchmarks don't really prove much as it can EASILY be swayed in one direction or another. These are just very basic operations, not going to benchmark the frameworks because that's unfair. I'll explain why later.

I tested : Apache Webserver + mod_php5 and Zend vs Resin 3.0.19 w/ JDK5 on a Dual Core Intel Mac 1.5 gigs of RAM.

For testing I used ab (apachebench) which comes default with every apache installation. Basically a "dumb" client that hits a URL as fast as it can.

The command was:

ab -c 50 -n 10000

Which means, do 50 requests at a time, and complete 10,000 requests. This test isn't exactly the best because it's not really doing anything. Really only testing who can loop faster. Results are interesting though.


The scripts:

JSP:

<% 
for(Integer i =0; i < 10000; i++)
{
	
	out.println((i % 10));
}
%>

PHP

for($i =0; $i < 10000; $i++)
{
	echo $i % 10;
}


?>

PHP Results:

260.68 requests per second. Took 38 seconds to service 10000 requests (50 concurrent users at a time)

Wow, amazing isn't it!? Remember kids, benchmarks don't always tell the whole story. We'll find out why next episode. If you have any comments or suggestions you may write me, jerome AT blackdood DOT com.
