Default LAMP Templating/CMS Performance

I recently started working on a new CMS system, that will hopefully grow into something robust enough that can be reusable in a production environment. One of the things I was concerned with was the performance using various methods. I wanted to make sure I could implement something that has a lot of features, but not a sacrifice in performance. I also wanted to minimize server load as much as possible.

Although the tests I ran were pretty elementary, it at least gave me a decent idea of how each method performed. I wasn't too surprised at the results, but the processing time of each method did have a larger margin than expected.

I had a discussion about this a few months ago on the devshed forums (which is a very good resource IMO).


Here is a breakdown of the methods discussed:

Method 1: Base template is your typical generic HTML page. The page contains specific areas where dynamic content is output.
1. The page data is loaded using fopen() or file_get_contents()
2. the dynamic content is generated coming from MySQL.
3. The content is injected using a simple find a replace type method using str_replace().
Before: {{BODYMAIN}}
After: <p>the quick brown fox jumps over the lazy dog</p> {{BODYMAIN}}
The process is reiterated until all dynamic bits are processed then injected into the template.
4. The modified document is output, page displays in users browser.

Method 2: Base template is a PHP page. The page contains a series of echo statements where the already processed dynamic content is output.
PHP Code:
//The PHP page
= xContent::getTitle('main');
$myBlog = xContent::getContentBasic('homeNews', 'xnTwoArticle', 'id', 'ASC', '0, 10');

// The HTML Page
<title><?php echo $pgTitle; ?></title>
<script type="text/javascript" src="./lib/js/myScript.js"></script>
<link rel="stylesheet" type="text/css" href="./tpl/myTpl/style.css" />
<body class="mytpl">
<table width="60%">
    <th>My Blog</th>
    <td><?php echo $myBlog; ?></td>
Method 3 (not tested): There is no template. All the static and dynamic content is contained in the database.

Here is a general flowchart of how each step method is done.

Luckily, I already have a codebase that is geared toward Method 1, so all I had to do is code something like Method 2.

So I did and ran some benchmarks today. Each page contained the same exact dynamic content and the templates themselves are the same, just processed differently.

System Testbed:
OS: Debian Squeeze 6.0
Kernel: 2.6.32 686
Apache: 2.2.14 with Suhosin Patch 0.9.8
PHP: 5.3.1-5 (using mysqli extension)
MySQL: 5.1.44

CPU: AMD Athlon 64 4000+ San Diego
RAM: 1GB DDR400 3-3-3-8 2T (for stability)
Chipset: nForce4 SLI x16


Method 1:
Fastest: 0.0042ms
Average: 0.00445ms
Slowest: 0.0049ms
Method 2:
Fastest: 0.0021ms
Average: 0.0023ms
Slowest: 0.0027ms
Well, there you have it!
