WordPress: Zend Server CE vs. cPanel & Apache stacks
I recently decided to install Zend Server CE on my machine to use as a local development environment. I chose the PHP 5.3 installation so I could update my PHP code to fit the new version. I was intrigued and excited to find that WordPress used a mere 2 MB of memory compared with 12-13 MB on my production installation.
| Zend Server CE | cPanel/Other Stacks | |
|---|---|---|
| Memory usage | 1.5-2 MB | 12-14 MB |
| OS | Windows XP Windows Server 2003 |
Linux Windows XP Windows Server 2003 |
| Installation | PHP 5.2.10/5.3 MySQL Apache 2.2.12 (Full) |
PHP 5.2.10 MySQL Apache 2.2.xx |
| WordPress Version | 2.8.4 | 2.8.4 |
| WordPress Plugins | Same | Same |
My primary testing was done on Windows Server 2003. Before installing Zend Server CE, WordPress was taking up what I would call an average amount of memory, 12 MB. After installing Zend Server CE with PHP 5.2.10, I found that peak memory usage went down to around 4 MB. After I found PHP 5.2.10 worked, I upgraded to 5.3, which resulted in yet another performance increase, bringing us to 2 MB peak memory usage.

Thoughts: I can’t find anything drastically different about the two installations, but I could be missing something. If anyone can solve this mystery, please comment!

After four release candidates, we finally have a stable PHP 5.3.1 release. For those already running PHP 5.3.0, there’s not much that is different, but there are some improvements. For others, it means there will probably be PHP 5.3 support in cPanel/WHM via EasyApache very soon. In PHP 5.3.1, the max_file_uploads directive was introduced into [...]

About two weeks ago, I wrote a short article called eAccelerator reduces WordPress memory usage which outlined how I was able to reduce WP memory usage to 8MB. While looking into the Zend Framework, I came across Zend Optimizer again, which I hadn’t messed with in a while. I decided to install it on a [...]

Recently, I switched to Zend Server CE from a manually installed AMP package (Apache/MySQL/PHP) to make use of Zend’s lightweight environment and easy install package. In doing this, I found that it broke the permalinks associated with WordPress. Despite mod_rewrite being enabled, and the “Pretty Permalinks” code being in the .htaccess file, it still didn’t [...]

If you install APC or another byte code cache in your CPanel stack, the memory usage will be very similar. And of course, your wordpress or any other app will run faster.

Thanks so much for the reply. I’ve been wondering about this. Is the Zend Data Cache component the byte code caching system or is it something else?
Any sites you would recommend on learning more about this?

@admin
Yes, Zend Data Cache is a byte code cache that comes with Zend Server CE, and is similar to APC

The byte code caching component in Zend Server is the Optimizer Plus.
Data cache supplies API to cache data between requests (and PHP processes)
